Not Good

For GV18 Smart Bluetooth Wristwatch

The watch was bricked from the get go. Plugged it in and charged it as the instructions suggested, actually charged it for 3 hours instead of 2. Hit the power button, and nothing. I have not contacted the seller directly yet. I will add to this review if they contact me and update.

Very Very Poor

For GV18 Smart Bluetooth Wristwatch

It’s strange that I should be asked to feedback on my order, as yet some 6 weeks after ordering the items they still have not arrived. I have had promises but to date no item delivered!!
So short of asking for my money back, there is not a lot that I can say, other than…. “WHERE ARE THE ITEMS THAT I ORDERED and WHY IS IT TAKING SO LONG!!!

Not really Arduino compatible

For Arduino Compatible SD Card Reader

If you are planning to use this product with an Arduino, be aware that SD cards are 3v3 devices. It;s nice that the card can be powered from a 5V supply via an LDO, but it you need to be aware that SD cards expect no more than 3v3 volts on the IO pins. This didn't bother me as I was planning to use it for development on a 3v3 system.

Good products

For Arduino Compatible Nano Size Board

Shipping to United States took a little while but everything arrived in good shape so good experience and all. No communication was necessary and it seemed everything was shipped on time. I don't think the products necessarily need specific documentation since what I bought was some standard stuff, the 24mhz logic analyzer and two nano arduino boards. Thanks goes to the seller.

The best little digital oscilloscope available.

For Original JYE Tech DSO-SHELL DSO150 15001K DIY

This is my second JYE-DSO the first has been faultless for a couple of years now. I use them more often than my standard mains oscilloscopes because they are just easier to fire it up off a 9v battery and take up far less work space than my bench units. There are limits (200KHz, 5mV-20volts/div, 500Seconds-10uSecs timebase) but for maker projects they are well suited. A steady hand when putting the kit together and average+ soldering skills helps but no surface mount components in the 15001K kit.

The display of frequency, voltage (P-P and RMS) and duty cycle is great for Arduino or ESP8266 debugging (particularly PWM outputs) and the triggering is stable. A 10Xprobe extends them for mains-level or Vacuum tube applications, so get one of those to complete your kit.

This last unit arrived two weeks earlier than expected - a definite plus - I was keen to get it up and running.
