I dont even have one of these but I own a repair shop and have a customer who has one. I suspect the unit is causing an AMP draw and need to disconnect it. This is how long it took just to get someone on the phone. Looking at the other reviews I should consider myself lucky. They better be extremely low cost to make up for the lack of customer service. BTW just got off the phone-elapsed time 1hour 15 minutes and still cannot disconnect it
