    Love these flashes! They are cheap and with these YN660 matching the power of high end Nikon and Canon flashes with a GN66 guide Number these are definitely worth trying out. They work great with the YN560-TX Flash Trigger. These are manual flashes only, n TTL but that's the best way to shoot a flash when doing studio lighting and it forces you to learn how to properly use a flash. They do warn you in the manual not to shoot continuously on full power or you can burn out the flash but these put out more than enough power at the lower power setting so you can fire away pretty rapidly and still have plenty of light power if you need it.

    These guys make some great speedlights. I can't for the life of me see why you would spend so much more for the big manufacturer ones. I don't think there is a discernible difference in quality. Definitely not one to justify the 3X price. I'd buy Yongnuo again in a heartbeat. In fact getting this light helped me realize I'd like another off camera flash for fill shadows and general experimentation. I constantly read about pros who use these. I'm impressed with the quality and the versatility. Even more impressed with the price

    Great speed light for the price. Compared to the Youngnuo mark iiii these things are a lot bigger. which is not bad but with a battery grip on camera and this flash it does add weight to the camera. Also most precut gels won't work. I control my 660s with the YN560tx and they work great but they will not zoom pass 105mm when controlled by the 560 tx, not a big deal to me at all but when they come out with a 660tx I will upgrade from the 560tx. Last thing. A Nikon or cannon top of the line speed light cost over $600 - $700 I can buy 4 YN660s, 4 battery packs, 4 light stands and 4 NEEWER 32x32 softboxes with removable grids for the price of one Nikon or Cannon speed light. This is a no brainier. These things are built solid, and does not feel cheap. But lets just say within a year they do clunk out. its only $75 I can replace this with out breaking the bank.

    It seemed to work great for about a week, then quit. In all fairness, the unit worked perfectly in all modes when I removed it from the camera hot shoe. Dazed and frustrated I sent the unit back, but have since determined that the camera hot shoe connection is the culprit, NOT the flash. I shoot almost entirely in manual mode, so this was the perfect flash for me. Once I get the hot shoe dilemma resolved, I will likely re-purchase this flash. It's a big flash with a ton of power, and would suit my needs to a T. Great value for the money too!

    Love it! This is my first flash I bought, so wanted to go with this instead of one of the $500 Canon ones. It's very easy to use and understand, and so far is doing great! Cheap price with excellent features and build. I'm definitely buying another one soo to add to my gear. Only issue for me is that it doesnt lock down super tight on one of my wireless receivers, but other than that its great!

    I'm using it mostly manual and it's great so far the price was awesome compared to the other competitions it's a great choice the sensor works great and it catches the flashlight quickly in some cases even better than Nikon SB 910

    My initial tests and usuage has found this flash to be an excellent performer. It has more power than any flash I have used. Recycling time is also excellent.

    This is a very nice flash, but was just too large for my camera body. I have a Canon EOS Rebel SL1, which is a smaller entry level professional camera and this flash was super heavy on it. I ordered a slightly smaller flash by YongNuo to replace this one.

    Fantastic piece of equipment! I don't know how Yongnuo builds their flashes as well as they do at the price point they are sold at. I have 2 YN560 flash units which have never let me down and this unit is even better!

    I've used Nikon SB800 for years. I have 7 of them. I've replaced them with 5 of these YN660. They are powerful, well built and easy to navigate. Better than my Nikons.

    Great Power for the money! I love Yongnuo flashes, but the only thing that bothered me, was that this flash did not come with the stand. I have purchased the YN 560II, and the YN 685, and they came with the stand. I would have given 5 stars if they had included the stand. I plan to purchase more YN 660's, but not from this seller.

    This is a worthwhile update to the YN560. Extra power does come in handy at times. However, this is a large flash unit. Well made and sturdy, just on the large size.
