Best mouse and keyboard?

I've got a Corsair M60 mouse and I absolutely love it. Keyboard is a Microsoft Sidewinder X6 which I really like too. My headset is a Roccat Kave, which I 100% recommend to everyone.

I use the "Roccat Kone XTD" and im VERY HAPPY with ist,
since yesterday i use as keyboard the "Roccat Valo"..
together they are not rly expensive but i think thast they both are its worth !

As for the tittle, which are best is objective, and depends on a few factors. As for the ones I'm using:
Mice: Logitech G500. Bought it because I couldn't find steelseries sensei in stock, can't say anything bad about it other than that it's ergonomic, meaning you'll have trouble using it if you are left-handed.
Keyboard: Shitty one that came with the pc, I don't even know the model, some generic genius.

if your a gamer, getting "Logitech Trackman® Marble" mouse is a must, its accuracy and precision is unstoppable once you master the feel, first person shooter games will become to easy for you with this mouse. its a must have

Das or Filco keyboard, razer deathadder or logitech mx518

Trust

Razer

i bought an Sharkoon Keyboard and a Roccat Mouse for some days, Hope they are coming in 2 days. My XBOX 360 gamepad was already here

Razer DeathAdder + Thermaltake Meka G1

I love my Razer Naga and my keyboard is from 1995.

For keyboard I use the one from MK520 Logitech combo, it has nice low profile and it's reasonably quite, could be quieter though. My mouse is G400, quite a nice mouse, I liked MX518 a bit more, mostly because it had lighter scroll wheel.

I have the Logitech G100 keyboard and G700 wireless gaming mouse. Both are amazing, responsive, and feel great. Love them.

I needed an ambidextrous mouse and my Steelseries Kana has treated me oh so right. Lovin it so far. As for keyboards, I'm in the same boat as you, still looking for one.

Mouse: Deathadder
Keyboard: Blackwidow
Headset: Logitech G35

All serve me great and perfectly. G35 is $100, comfortable, surround sound enabled, has high quality sound, has 3 rotatable head cushions, and you can uesr them as speakers by going max volume.

using logitech since years

...

Logitech was amazing once, but this times are over - except you have no problem buying expensive stuff that breaks after 1-2 years without particular reason

For example I had to return my first g700 because the laser stopped working every once in a while - after 4 months ... my newer g700 also starts having that problem after 1 1/2 years - to compare that, my old mx510 was/is fucking indestrucktable and still working after ... 7 years, 5 of them torturing the shit out of it (lan party's and exessive gaming back in that good old school days) - i just retired it because it got too messy to clean it =P

I also had the g15 keyboard (the first one) - except the fact it started blinking sometimes when the pc was shut down, it is/was a good keyboard - after 5 years i retired it and got that G510 - also blinking when the pc is shut down, you cant control itunes anymore when you are ingame (what is fucking stupid since the g15 was able to, gj there logitech) - oh and the integrated soundcard suddenly stopped working a month ago...

TL;DR Dont get Logitech stuff now

Microsoft Sidewinder X4 keybord. Because of antighosting, macros and 4 steps of key illumination. And it looks good.
Mouse - well, I've got G500 and I like it.

I'm about to get a Logitech G600 mouse. From what I've heard it's pretty good and has many buttons that are pretty useful for my work.

Steelseries Sensei + Steelseries 6GV2

I got razer deathadder 2013 combined with razer vespula BEAST COMBINATION

Mouse: DeathAdder (or the Naga if you want to have ~12 extra keys); Keyboard: CM Storm Quickfire and the Headset: SteelSeries Siberia V2 or the Corsair Vengeance 1500 (I prefer the Corsair one but havent made a physical comparison with them both; tried them out at different events/dont have a friend that has the Siberia V2 yet to do it instantly)

R.A.T. 7 and S.T.R.I.K.E. 7 from Madcatz Cyborg.

Mouse - Logitech RX1000;
Keyboard - Steelseries SHIFT;
Headset - CAVIMANUS HS-G700V.

I have a Cyborg R.A.T 7 mouse, which I absolutely love! Customizable in both width, height, weight and length with sniper button and 3 profile with customizable DPI and key-bindings
