These do not work with all apps. In fact, many apps fail to fuction well if at all. The keyboard is rickety. So is the mouse pad. Some sites or apps won't allow you to scroll on this chromebook when you should be able to. The cover is a vinal sticker. The google circle is missing off one. They are very clearly refurbished OLDER models. I wish I had read this more carefully. Don't buy this uless all you need is simple internet use and simple word processing. It can't do much else very well. Not even really suitable for young kids, which is who I purchased it for.
