Dear customers,

Thousands of units were sold to users in 23 countries.

THANK YOU !!!

Due to personal reasons and a lack of Marketing skills to take this to the next level (new version with more features USBcheck V2.0) I have decided to sell or license the patent along with the all the domain names.

“The tester works great. I lost a memory stick because the connector to the motherboard was labelled wrong. The tester solved the problem. I now carry it with me and always test a computer before I put in my memory stick, just to be safe.”

– Robert R.  – USA

“We had 3 problems with reversed polarity with computers that were brought in for repair, which destroyed 3 flash drives in our shop. Now, we just test the USB port before using our USB devices and we don’t even have to open the case and check the connections.Thanks!”
