I bought this to replace my tower hard drive with a unit that used windows 10. It worked well for a week, however it was very slow. After two weeks, it wouldn’t type any longer, no matter how I tried to figure out what the problem was, I couldn’t. When I tried to turn it off today, it said someone else was using it and not to turn it off! It will be returned this weekend.However the company has offered me a new and improved version to try for free.So I guess this is a good company after all!
