I have used these machines in work, so wanted my own one for home use, it was received quickly however, the keys were replaced with cheap ones, the board that holds the keys was raised and cracked, andnit would not charge correctly. It would charge for a few minutes and then register at 100 percent but once removed from power source it would read as just 10 percent....... In the process of a return now that I have to pay for upfront and claim later so really not impressed
