Most of the time this has worked fine for us. Occasionally, though, I'll have an issue where it simply won't come on. I finally figured out after the first time that the power cord needs "jiggling" around from side to side to get it to come on. I had pulled every single cord out and put it back in tightly before discovering what it needed. The slightest bump to the tower will turn it back off, too, which is annoying. It's mainly used for my children's school lessons, so they then have to wait for it to reboot after turning it back on. We've pushed it back, so it won't get bumped as often, but it still happens. I don't overly trust the thing.
