The power adapter on my tablet PC broke, and I went to these guys to get it fixed. They replaced the parts once, turns out they got the wrong part. Attempt number 2, they got the wrong part again. Third time was the charm, and they got my laptop working again. For a month. Now the tip snapped off the power adapter that they sold me(for quite a bit of money), and I am right back where I started, but out over 100 bucks for my troubles. Would definitely not recommend.
