I started to have a problem 3 weeks ago when the Vtab stopped connecting with my PC for file transfers. Then last weekend it would not charge unless the cable was pulled toward me. I called Vizio and they had me try a phone charger and cable but I had the same result, no charging unless I pulled the cable toward me. They will replace the unit and are eager to do so but I still have a 5 day window to return it to Costco for a refund. I did ask the rep if the new / refurbished unit was re-engineered to fix the problem and the answer was not to her knowledge. So after reading about others with this issue I think I'll return it and go back to my 7 inch Coby that has worked flawlessly for 14 months but does not have all the bells and whistles of the Vizio and wait to see what Vizio comes out with next that might be more durable.
