Here's my freshly bought MCUmall GQ-4X Willem Programmer. It's a really poorly manufactured product which has poor contact on USB connector.
In addition to not functioning, it made a short circuit and broke one of my HDD.
I had to write 30 emails to get it replaced and receive it 4 month after buying it ! The second one broke after one programming ([ Ссылка ]) -_-
MCUmall has asked me to pay back and forth shipping fees to repair it even if it's a brand new product !
The worst purchase of my life !
