Their products are CRAP! The site states 100% money back guarantee, this is a lie. They will tell you that you have to ship back to them, in China, at your cost for any type of refund and ONLY if the product is what they deem as defective. WARNING: If you pay through PayPal, PP will side with them because it states on thier website that you have to ship back for a refund. It will likely cost you more to return than the product is worth.
