People are weird when it comes to ensuring they get absolute maximum value out of the things they buy. I had a 3 year old $20 electric shaver that got dropped into water a few months ago. It wasn't water proof. It stopped turning on but I noticed if I let the battery drain and then plug it into an outlet it worked. I got about a month out of it this way. After it stopped working using that method I tried every day for a week using all sorts of combinations to see if it would turn on, it never did. Eventually I bought a new one but I wasn't happy about it.
