Since I have had this, it has suddenly went black screen on me multiple times. It jumps up and down when trying to read something, it had an update called firmware,,that is still saying it's  updating everything I  turn it on and it is extremely slow. Had I known all of this ,I never would have purchased it, because I cannot uninstall the update, and I cannot seem to get or find any help in trying to fix this issue. Very unsatisfied with this,, will never buy another Ascer .
