Marco P. 5 I decided to buy this to change my car cigarette lighter plug with this one. The item is great, but I just don't like it where it turns on when I start my car and if I don't use it I turned it off. So everyday, I have to manually turn it off because it always comes on when I start my car. I hope the change the default setting of OFF instead of ON. Also by changing it from cigarette lighter plug to USB, I prevent some devices to be plugged in such as cigarettes' plug in devices like laptop charger (12VDC), vacuum, etc. But overall, great product.
