Plugged it into my car and it worked great for one week
I have had the product for one week.  Plugged it into my car and it worked great for one week, made a noise and went dead.  I am leaving on a road trip for 5 months tomorrow, 6/29/17, and really needed this for my back, but I wasted my money.  Do not recommend it to anyone.  Very disappointed.
