    I've owned this product for about 3 months now and I just fallen in love with it. I own 3 Pocketwizards II which I use with my studio lights but I've been looking for a trigger cable which would trigger the camera and flash simultaneously. That set up for Pocketwizard would have cost me about 60 to over 100 bucks alone so I took a chance with the Yongnuo's. I got the 2 Trigger package which came with a shutter release cable for about 30 bucks. I love it so much that I ordered another set for a 2 light set up and wireless trigger system. I've read many negative reviews on where people are having trouble putting the flash on it and securing it on the light stand! Not to be rude or anything but those people should probably stick to natural lighting or educate themselves more on how to properly set up a lighting system. The only negative thing about the trigger would be that you have to turn it on before you mount the flash but beside that love those little buggers!

    Bought a pair of these a while back and got another pair as a backup. Old and new units play together nicely if set to the same frequency (of course). I can now trigger three flash packs/monolights/speedlights without relying on optical slaves, which don't work in an event since every casual shooter is using a flash. These are reliable, do what they should, and are one of the few decent looking products of its type out there. Most are terribly styled and look like hobby grade junk, which in fact what most of these things are. You can at least get away with using a cheap radio trigger without looking like a total noob. I first started using these with older Speedotron pro gear in my studio, to protect my DSLRs from the high trigger voltage. Never failed and saw no reason to go to the more expensive Pocket Wizard triggers since I don't need any more than basic features.

    My RF-602 triggers are aging and that CR2 battery is a real PITA, so I thought I'd try picking up a set of the RF-603II triggers not only for the numerous improvements (locking ring, on/mode switch on the SIDE of the unit, the test button working in hand, etc.) but because these would be compatible without modification with my micro four-thirds camera (Panasonic G3). Worked great out of the box on both my Canon and Panasonic cameras. But. Whether I got a bad unit or a bad cable, I don't know, but the set could not be used as a shutter release with my 50D and 5DMkII, so I am returning them. In addition, I could not get another feature that was mentioned in the specs to work at all, which was the use of the PC port as a triggering input (from, say, a camera's PC port or a light meter) in Tx mode. I like to use a small optical slave in conjunction with the pop-up flash of my Powershot S90 to do radio off-camera flash triggering sometimes (I'm just weird that way), and it works fine with my RF-602s (which are old enough to still have the PC input port on the Tx unit). Couldn't get it to work. And the manual that came with the triggers describe the PC port as an output only (just like on the Mk I 603s). So if this was the feature you wanted the triggers for, you may want to wait and see if anybody reports success on this. Other than that, the triggers were great are popping off remote flashes in my testing, and I'm sorry the other features didn't work as I expected them to.

    I'm using these to trigger multiple Yongnuo YN560 IV speedlight strobes with built-in receivers and they work flawlessly. Since the speedlights have the receivers built in, you only need one of these mounted in the camera hot shoe. If using a speedlight without a compatible receiver built in, you can use the second RF-603 II to fire it. I just keep the second one as a spare trigger. I also have the Yongnuo YN560-TX flash commander which triggers the same strobes, but also allows you to adjust the flash output and other flash settings. The YN560-TX also sits in the camera hot shoe but is considerably larger. However, it will still make all the flash adjustments even if it's not mounted on your camera. So I find it useful to make the adjustments using the YN560-TX commander which I can keep in my pocket and put the RF-603 II on the camera and stay streamlined.

    I use the RF-603 with my YN565ex and my Canon T3i. Initially I was a little frustrated getting these set up but once done I must say they work very well. The frustration had s much to do with my big fingers as it did with the actual transmitters. I fired about 100 test shots and they didn't miss once. I didn't do a distance test yet but they did trigger the flash while the camera was in another room with a wall between them. Works well as a wireless remote to fire the camera (say for long exposure night shots) and considering the cost of a wired trigger this feature makes the unit worth buying unto itself. This is an excellent value whether you are on a budget or not. They get the job done for a low cost which allows you to put that money into things where money should be spent...like lenses.

    If you are looking for a budget flash trigger, look no further. For the price, these just can't be beat. Some of the things I really like about these: Small, takes AAA batteries Work at great distances, a 100m actually seems accurate Triggers each time (tested for two days, about 1000 shots and fired every time) Each trigger can be used as a transmitter or transceiver (transmit and receive), great for when you want to use a light meter On and Off switch on the side (actually switch between OFF, TX, TRX) 1/320 sync speed, I could only test with my Canon 7D at 1/250th Comes with cable for triggering camera remotely, make sure to get correct model for you camera (C1, C3, N1, etc...) Has a Nut so it can be tightened to camera and/or flash Works with Yongnuo 560III So far I have not found anything I don't like about these. Make sure to get Yongnuo RF603 II, the originals RF603 do not have the same options. Ok, so I've had these for several months now, they are still working great, I've even ordered a few more, have about 8 now. The distance that these triggers work is amazing, inside and outdoors.

    Have tried to order these before and a different company sent the wrong model...or then I tried a different brand and they misfired more than they worked. Finally I was able to get these and I am thrilled with them. I have used these twice so far and I do not think I have had any misfires.Have also used it as a remote trigger..,both devices seems to have to be set to TRx to make the trigger function work that was not obvious from the devices nor from the manuals. The other thing that is cool is that I have a yungnuo 560 flash and the device will fire that without a receiver on it....so with the two devices I can trigger both of my speedlights.

    Camera: Sony a6000. Flash: Neewer TT 560 Speedlite Just got these wireless triggers today. Read the manual to get the settings right. They work as intended for an off camera flash. No need to modify the device or camera's flash plate. Sync flash and rear flash modes wor with this trigger, and both modes work without a PC cable. Be aware that the verision I got comes with an N1 2.5mm cable that allows PC connection for nikon camera. Sony mirrorless users can ignore this cable entirely as it is not compatible and will not improve the function of the triggers for Sony mirrorless users. Happy Shooting!

    I am very happy with these flash triggers. I have had no problem with the trigger setting off the flash when I am not taking a picture, a problem I had with a different brand. Occasionally the flash will not trigger but I think that is to be expected. They have a solid build and are low profile. My only complaint and why I did not give 5 stars is that I can not trigger the flash for meter readings unless the unit is connected to the camera and I have half pressed the shutter button and then push the test fire button. Its a pain to do all that with one hand while I hold the meter in front of someones face with the other. I would buy these again.

    I was excited to see Yongnuo introduce a new model - I love their flashes, the CTR-301P transmitters and the RF-602 transmitters. The RF-603 is their newest generation of wireless flash transmitters -- they look similar to the RF-602 receivers, but go for a new route. Rather than a Transmitter and Receiver, these are "Transceivers" - meaning they do BOTH. If you buy 4 of them, you can put 3 on different cameras (as transmitters) and 1 on a flash (as a receiver), or put 1 on a camera (transmitter) and 3 on flashes (receivers), or any combination. With the RF-602's I bought 3 receivers and 3 transmitters (for the times I use multiple cameras), this would have allowed me to purchase fewer. Similar idea to the PocketWizards. The RF-603's (like the 602's) can also act as a wireless camera shutter release -- plug the release cable (one is included -- make sure you get the right one for your camera) into a receiver and connect it to a camera, and use the other transceiver to trigger it (by pressing the button on it --

    these guys (i have 4) have allowed me to really change the way i light and take pictures. i use external lights manually (the YN560 strobes are my tool of choice) so i really don't care about ETTL or IR focus of the fancier models. at this price these guys are virtually disposable, though i haven't broken one yet. i use rechargeable batteries, and these units inevitably outlast the speedlights on battery power. they would get 5 stars if the on/off switch wasn't so easy to bump on in the bag, and especially if i could get TO it with the strobe mounted. but at this price, i am delighted with their performance. GET THAT FLASH OFF YOUR CAMERA WHERE IT CAN REALLY WORK FOR YOU! just do it. and forget the cheap duo-fold westcott umbrellas. talk about design obsolescence. get the single-fold photoflex with they nylon ribs. da bomB!

    I was shocked they arrived so soon, but felt incredibly blessed they did since I'm leaving for a huge photo tour in July and heading to the coast of California...I needed some triggers for surfer/ocean/night/star/sky shots.... Yongnue RF-603 triggers fit nicely and work well with my Canon 50D. I've worked with several types of triggers in the past in a studio and these fit nicely in your hand and in the hot shoe of my camera. I would highly recommend them to my photography buddies; they were recommended to me from a pro which is why I purchased them.

    I was a little skeptic in buying this product but once I did I was really surprised with how easy it is to use and how well it work. The first time using this product I was shooting an engagement shoot and the only issue I found was that there was another photographer at the venue. it seemed that he had either the same transmitter or was transmitting on the same frequency as I because I was noticing that my 430X II was being triggered when I was not taking pictures. I was able to work around it. This may be a problem depending the situation but it was something I saw this may be an issue for some people. My photo session was outdoors and the flash was being used as a fill light.

    These are great. I was stuck with a flash and a camera that could not operate in "master" mode and considering buying an expensive master flash. I knew these type of things existed, but most are in the hundreds of dollar range. These are an amazing value, well made, and very reliable. HOWEVER, there is no hot shoe lock. No lever, no screw down, so they very easily wiggle out of the hot shoe and cause the flash not to function. I learned to push the trigger in to the hot shoe on my camera before each shot, but that is a bit tedious. I am not sure why it won't lock; it's fine with a flash on a flash stand, but one has to go on your camera hot shoe and should be able to be secured. Regardless, I would highly recommend these, I'd had many pros tell me they are just as good as the "big names!"

    After unwrapping them and installing two AAA batteries in each of them, was snapping pictures within minutes using my 7D and four flashes in manual mode: Two YN-560's One Canon 430EX One Canon 580EX II That left one RF-603 unit free to use as an off-camera shutter release. A much better solution (in my opinion) than the Canon RC1 infrared shutter release that I also own. There were no configuration issues, simply put batteries in them, plug them into the speedlights, and they work. I love it when stuff just works. The lack of a securing pin on the RF-603 to a hot-shoe is not an issue for me. The unit stays secure on my camera through spring-compression of the contacts. The 603's stay secured to my light stands through the stand's clamps, and each of my speedlights have a clamp that keep them secured to the top of the RF-603 units. I also do not have an issue with the dip-switches being in the battery compartment. With the dip-switches in the battery compartment, they won't get accidentally moved around. A great value!

    These triggers will not work out-of-the-box with the Olympus OMD EM-1 camera. I purchased these triggers and a single Yongnuo YN-560-III speed light with the hopes of using them as an off-camera flash system. I intended to put one trigger on my camera and then use the internal receiver of the 560 as the other. I'll keep this short - the YN 560 flash works great on the OMD. No problems at all so go ahead and get that flash if you're looking for a good flash (it will be full manual with no TTL). However, the 603 trigger's pins are not configured correctly such that the OMD can trigger them when the shutter is pressed. Fear not, if you can solder or know someone who can then you can mend this issue in ten minutes.

    I was impressed by these little guys. Not one misfire and just works. Not going to brag about the low cost or the fact that build quality is outstanding, but will just simply say they work great. I will be buying a couple more just to have multiple points of light. I plan on buying at least two yongnuo flash lights YN560 III is just a great partner. I modified the RF-603 to work with Sony NEX-6 and wow!!! this is just such a great product. Buy it before they run out!!! I am placing another order now. BTW, I am a photographer which has been using high end ProSummer equipment since early 80s. I am impressed.

    I'll put it simply. These are terrific, never missed a shot triggers. The best part is they are supplied with a shutter release cable for your specific camera. I have ordered 3 sets total so my daughter and I both have 3 each...one on the camera, for both shutter release and flash, second on the flash itself and third one for the hand held remote trigger. However, there is no securing lock or screw...whatever you call it...that secures it to a base on a light stand. It also does not have a screw hole in bottom for a light stand. Great trigger that I think they will redesign to add those problems I've seen reviewed elsewhere. Buy them anyway. Inexpensive and operates flawlessly.

    I have 6 of these. 4 of the old style and now two of the new. They are reliable and compact and work with any camera when paired with the right cable. I mostly use them to trigger my camera but they can also be used to trigger strobes. I am glad to see the power switch has been moved to the side so you can reach it when something is mounted above the trigger. Now if they can make the battery doors not fall apart when dropped that would make this review 5 stars. I dropped one and broke the clip on the battery door the first day I got these new ones. Out of the 6 triggers I have, 4 of the battery doors are broken and I have to tape them on. Hey Yongnuo, fix that and these would be nearly perfect.
