After one month of use, it stopped working....Do not waste your money on this poorly made product, the customer service is aweful and the product sucks also. The seller even refused to refund my money, which was an insult they should have at least given me a credit for the unused product. DO NOT BUY THIS PIECE OF WEIGHTLESS. I would give it zero stars if i could. SAVE YOUR MONEY!!!! YOU HAVE BEEN WARNED!
