I put the maximum score to Duragadget because after sale service has been perfect and responded to my email very quickly (spindle to ensure compatibility of the adapter with the recent model of my tablet). Duragadget then sent me a new charger compatible with my tablet, but I have had to return their previous charger. Great service and very good people. no complaints. Very correct delivery times. I recommmande all this business (Duragadget).
