Mega 2560 worked for me
I didn't notice all the one start review when I placed the order. So when I started trying the board after reading all those reviews, I really worried. On the first try, I could not download a test program from Arduino IDE either. I went to Tools->Port and selected the serial port, still didn't work. Then I went to Tools->Board and found Uno board is by default selected. I changed the board to Arduino Mega or Mega 2560, then I could download program successfully. I only tested the blink program with different delays. Will update if I find something not working

Arduino usb port was flakey just reflowed the solder points
After seeing the reviews on this I was prepared for a doa arduiono but I mostly just wanted the ramps board drivers and lcd screen so purchased it anyway. The packaging was above what I expected all parts were individualy wrapped and it came in a nice reausable case and yes my arduiono was doa. It failed halfway thru the first flash then the pc didn't recognize it at all. I was able to flash it using another arduiono ao I figured it's the usb port so I reflowed the solder on it and now it works. I probably won't use this arduiono on my project but all the other parts worked fine out of the box.

Not working....
Not working. Shows up as a device, everything lights up and no noticeable defects... can’t get anything working through the arduino program on PC... still trying, will be sending back if unable to resolve within a few days.

A good product
ANY instructions would have been useful it came with absolutely zero instructions at all. Setup was rather difficult but the printer is working now thanks to YOUTUBE. EDIT less than 1 week and the FAKE arduino has failed

Bootlegged Arduino Mega Board
I would rate this 0 stars. Bootlegged Arduino Mega 2560 board. My laptop didn't recomend the arduino mega. I couldn't even upload the mega driver to the board. The Ramp 1.4V board was dirty with flux. Not pleased with this product at all. I decided to buy the name brand board.

Died shortly after use
Firstly, the drivers never were able to microstep the motors, which reduced the resolution by 16x and a couple of weeks after using it, it just straight up died

nothing is put togeather at all
I did not like that it was nothing at all was put togeather

Dont purchase
Mega 2560 stopped taking uploads. Solder connection on usb port was shorted when I first got it. I would not purchase again
