I used Splat's Pink Fetish, which worked wonderfully to turn my hair into radioactive pink. Granted, this product will work differently for different people.

It is thick and comfortable, seems durable and well made, doesn't smell much contrary to a cheap Chinese knockoff i first tried to buy on Ebay. That one didn't make it in the house as it smelled so bad of burnt rubber and had to be tossed. This one is very ergonomic. The only thing I have to get use to is the fact that it is smaller than my previous mouse in circumference.
