    The kit I selected is great for beginners as the surface mount components were already installed and I only had to solder the thru hole parts. Everything worked for me the first time but the instructions also include troubleshooting tips if you need them. The oscilloscope itself is slow however (something like 200 KHz) which is not good for the use I wanted to give it (digital electronics) however it should be ok for Audio applications.

    Items like this will cost 3 or 4 times the price offered by S. CA where I live. I am a person who has just been exposed to an oscilloscope, and I am afraid of getting wet with my recently acquired Tectronix, so this little S / B is very suitable for learning my way, I will soon master Tectronix that I have mastered This!

    I bought the article, so I can finally check signals in my artisans. It is very suitable for that, as I generally did not want to buy a big Oszi. However, the Zusammebau despite instructions not for beginners geeinget! You need a pointed soldering tip to secure the SMD parts properly. But if you have done everything, you are happy as a monkey, everything works without great difficulty. The case was rather complicated to understand without instructions. However, it has been done quickly for something to try and make it. In addition, you have to buy a 9V power supply or have luck, that is still rum around! THIS KIT I can recommend to anyone who wants to practice * SMD soldering * a cheap Oszi needs * fun soldering in general has.

    The kit is okay so far. The frequency specification of max. 200 kHz cutoff frequency is greatly exaggerated. Even at 100 kHz, the signal is distorted so much that measurements do not yield meaningful values. (Compared with the right scope) For LF tasks, the device is quite useful. It is also used for me.

    Have fun assembling and trying. Very good step-by-step instructions. Top. The case is a bit tricky because there is no manual for this. Looks great.

    It is easy to rebuild. It would be better if I had young eyes looking for small solder joints. I work for the first time. He didn't organize the case, but it doesn't seem difficult. It would be better if you provided a picture of the case or some instructions.

    Funny kits are mounted. Quite complex, but can be used for truly basic problem solving. If you really want to give us a cheap range often, how much will I pay for a USB oscilloscope?

    Beautiful complete kit, built in 3 hours without stress and put into operation. A component tester did a good job of mapping. The assembly instructions are well structured and understandable. It was fun and will continue to serve you well, I'm sure.

    The manual is self-explanatory. Soldered together. The oscilloscope ran straightaway. Top part at a top price! Is great for getting started in the oscilloscope world. Unfortunately, the case is not accompanied by instructions on how to assemble the case together. YouTube helps. I'm very happy with the oscilloscope and had a lot of fun soldering.

    Arrived as planned, excellent components, assembled and tested it works very well and it is also quite stable, for my little electronics jobs it's fine. I recommend it to interested parties.

    An excellent kit, not for the faint hearted as it is a complex assembly process but when finished and fitted in a case a very satisfying feeling

    Very excited as this is such an affordable bit of kit that is has been out of reach for many casual hobbyists. Assembly can be intimidating as there are surface mount resistors to solder, requiring some skill. Some other variants of this kit may have the SMDs pre-soldered. Also resistors are difficult to identify due to their size so must be carefully measured before soldering. Soldering the 40 pin connector to LCD is also a challenge. Instructions provided were good and contains plenty of pictures to illustrate assembly. Troubleshooting flowchart also clear and helpful. The kit requires great care in soldering so definitely not for beginners, however with a little patience and courage (on my part) can be extremely satisfying to get working. Good value however no instructions on connecting through on USB port / UART which I assume enables data logging.
