I have a Logitech G502. It has a nice scroll wheel and really nice locations for buttons, but it is a little expensive. But if you don't want as many programmable buttons, if you can handle 4 dpi settings instead of 5 (lol),if you don't need 12,000 dpi (LOL), and if you don't want to change the weight of your mouse, just get the G402. It's basically the same mouse, just 20 dollars cheaper, but I've seen both, and they are both very nice mice.

I like mice with side-buttons so I can mash +duck with my thumb instead of my left-hand pinky.

I use a monoprice zowie-am now, it's like $30. My old mouse was some no-name 5-button piece of crap that I loved but the USB cord would stop working every now and then and I had to stop using it.

I'm using a WMO 1.1a on 125hz at the moment. I also have a Zowie Ec2-a and I prefer the WMO because it's way lighter and more comfortable and I hit more shots in Tf2 with it and have higher accuracy when I play Quake with it.

I have experience with multiple Zowies (ec2-a with omrons, za13, and monoprice am) and would recommend all of them. I'd also recommend a lot of Logitech mice (G100s, G400s, G303 if you can stand the shape, G402, and G502), I've used my brothers Deathadder and Intellimouse multiple times and I think they're pretty good too.

I'm currently using and have used a 2012 Deathadder since it came out. No problems so far. The quality on mine has been great. The side buttons still work perfect and there seems to be no wear and tear like I would have expected of a 4 year old mouse.

Sharkoon Shark Force

which mouse is better deathadder 2013 or chroma, im looking into buying one soon.

Steelseries Kinzu v3. Very cheap and good.

Zowie EC1-A

MX Master.

The Zowie FK1 makes my dick hard.

They're both fine just don't turn up the dpi super high on the chroma.

razer abyssus: shit sensor version

Razer DeadhAdder chroma, love it

Logitech G302, got it on sale and I haven't had a single problem.
People complain about the shape but personally it's great for my baby hands

Apple Magic Mouse, had it for 5 years now. If ur gonna get it, make sure you have a constant supply of batteries
EDIT: btw its wireless bluetooth and it has built in mouse accel i thinm

Corsair M65 RGB, won it in a comp which was nice since I could hardly afford a $10 Microsoft wired mouse let alone a gaming mouse

sounds to me like a worthy investment

Or you know...you could get a 10x better mouse with a 'proper' shape and an optical sensor for the same price or cheaper...

Steelseries Rival 100

Logitech G500, have had it for years and the only problem I've had is the dpi changing buttons have gotten kinda mushy over the years.

EC2-A

G303 and Rival 300

g303 is godlike and rival 300 only had rubber grip problems that are (hopefully) fixed

G502

Using the speedlink decus right now, really good palm grip mouse. A shame nobody really knows about it.

i still really don't understand why people bother with mouse specs and shape and all that. it's comfortable, it works, and i can play tf2 with it, no need to worry about all this fancy specs stuff

MSI DS200

I recomend zovia fk1 or logitech g series

DeathAdder/Finalmouse

currently broke all but one of my deathadders (5)
waiting for the ScreaM finalmouse to try it out

A mouse's low max tracking speed / irremovable accel can be the difference between a grand finals winning med drop headshot or completely missing your shot and losing the game. If you don't care about having perfect equipment you should be pubbing, not playing competitive video games.

these words can only come from someone who hasn't yet worried about all this fancy specs stuff
