Building the mouse Logitech won't make

Slightly off-topic, but while reading the article, I was reminded of the terribly bad mouse switches that Logitech has used in some of their products. They aren't hermetically sealed, and they corrode after a few years. It's almost as if the mouse was designed to self-destruct after the warranty expires...

The rubber parts on every mouse also seem designed to fall apart and get gross so you'll buy an new one.
