We purchased this to replace a month old Acer which had problems with the stylus and could not get Acer to fix it, long story. This unit works perfectly, my only gripe is that it has a lot of cheap looking plastic parts.Amazon delivery service gets a minus 5 stars for leaving the package outside our unlocked gate (no dogs in the house) exposed to the street. This is a recurring problem, they are too lazy to open the gate and leave the package behind a bush right by the gate. UPS & FedEx do a much better job.
