It cost me well over $20 freight to receive and open a package and look at the contents before I sent it back. The internal battery on the keyboard host was at a 44% wear level and while the tablet wear level was at 85% it was at 79% a few days later when I re-packaged it after around a 1 hour run time. Communications with the company were confusing and ambiguous. I can't see myself spending an amount like this on a re-furbished item again. It cost good money to get nothing. Also it was sold out until I returned it and then they had a stock of one again. I suppose eventually someone won't check the wear level on the batteries and will keep it.
