Microsoft P58-00029 - good'o high school memories, I still have 2 or 3 in the house that's for backup, i kicked so much ass in Counter Strike 1.5/1.6 vs people with their $80~$100+ mouse.
Logitech MX510 - got this from a really good friend of my from high school because he got a M9, i used this mouse till the buttons don't even click anymore. this was used right after P58-00029
Tt eSports Element - gaming, been using this since when it first came out, it been though hell and back with me... liquor of the choice at that time, orange juice ect. you name it. just had to dip it in a cup of water for a few hrs, and let it dry for about a week and its ready to go. NEVER actually had beer damage on it, don't drink beer.
Tt eSports Level 10m

Anything Razer
for the most part i don't really care how fancy or how nice mice are, as long as they work i can careless. unlike keyboards, i don't care if they light up, dps switch can be helpful but my hands can learn adapt to it it doesn't really matter.
