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.

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.

fair to poor

For LILYGO® T5 4.7 Inch E-paper ESP32-S3 Touch Screen

After waiting a month, my FM radio kits finally arrived. I guess shipping from the Indian Ocean / Sechelles added to the wait time. The documentation is in Chinese, which is totally useless to me.

nice collection of stuff, some of it I know what it is.

For UNO R3 Starter Kit 4 x 4 Keypad LCD1602 Servo

I am still looking for project examples using the components that I received in this bundle. This bundle included a genuine Arduinio Uno R3 board A plus, but no documentation on anything. I'll have to search the internet for sample projects and try to figure out what some of these components do.

Would be neat it fully worked

For Electronic Clock DIY Kit

When I finally got it in the mail, the memory chip pins were bent up and one broke off when trying to fix it. Also having a hard time to even get the clock to work properly. Everything is soldered correctly and clean but the clock will only light up one or two numbers and that's it. The speaker and buttons work just fine but everything else I just cant seem to get to work.

No documentation with display

For VHM-314 Bluetooth 5.0 Audio Receiver Board

Plus in order to contact the seller I need to sign up for Facebook. I am probably one of three people on the planet who are not using facebook.

Counterfeit FDTI chips used

For Nano V3.0 ATmega328P-AU Microcontroller Board

The build quality of boards is very cheap and most importantly the FTDI chips used in the boards are counterfeit.
