Query: It stopped working 3 days in.

I had it for three days and then it just stopped working. tested everything with a multi-meter and still couldnt figure it out. i returned it and the new one NEVER WORKED AT ALL. Then i returned that one and they didnt send me a new one, they sent me my money back, oh well.I would NOT recommend this product to anyone.
