This company sells JUNK! Their product does not work. I have contacted customer support numerous times due to a lack of any instructions regarding the use of the product I received without any instructions. At first they promised instructions would be sent within 24 hours, but none were evr received. After at least 2 other phoned calls and 3 emails requesting instructions I received an email message with instructions for a product I did not receive. Again, I made a number of attempts to tell them they were sending information for the wrong product, a product they never sent to me. I even went so far as to send them photos of what I received only to receive an answer that was operating the wrong product. I would seriouisly advise against anyone doing business with this company since I even question the ability of anyone to even read English and am extremely doubtful if they even know what they are doing. Without any written instructions their product is a piece of crap!
