It was good, because in past years if you ever lost batter connection, or had a incidental short somewhere when got hit.. you could not compete. Your controller would keep resetting and it was quite annoying. The backup batter kept it from being reset which was nice, and you didn't have to wait for the controller to boot up each time.

It didn't do any harm, only annoying part was having to charge it, which rarely happend.
