I use it every Friday. Our silly classroom only has a few electrical outlets on the walls, and every student has to have a laptop to view slides, study cases, and take exams. Not everyone has a 10 hour laptop battery so I bought one of these. It works. So far (a few months) no problems. I wish the outlets were spaced out a bit as some of the Macbook's charging boxes can take up a lot of space. But in this price range there is not much to complain about.
