I just got a Surface 3 pen for school about a week ago. Everything was fine, until I noticed a big dent near the top of it. It is impossible to get the AAAA battery out, because I think it dented the battery, too. Surprisingly, the pen still worked, with the battery dented. I tried to bend the pen the opposite way, and when I tried to use the pen after that, it just STOPPED. My mom spent a lot of money on this, and I hope there is a solution, because she doesn't know that it is broken, and I don't think I can return it.
