The Crest Spinbrush as it comes out of the package is easy to use, cleans your teeth quicker than traditional toothbrushes, is effective, very cheap (I've seen them for as little as $5), and only operates on 2 AA batteries. This is all very nice for about two weeks when you realize you will need to replace the batteries soon. After about a year of constantly changing batteries I decided to do a little tweaking and this "hack-brush" is the result. With the hacked spinbrush you will be able to clean your teeth even quicker than the original spinbrush, it will be more effective, and you will never need batteries again, saving you more money!

As stated in the article I could be standing in the rain using a plugged in drill and if it is plugged into a GFCI outlet the circuit will trip before any harm is done to me.
Thanks for your comments though, I made an edit in my ible to address this as I know many will have the same concerns.
