This is the perfect mouse shape for me. I used the Razer DeathAdder for a long time, and played well with it. I decided to try the Zowie EC2-A because it looked like a more comfortable shape and had good reviews.

-Great shape - similar to the DeathAdder, but more natural; The angle of the DeathAdder put more weight on the right side of my palm and wrist which didn't affect my aiming, but did make long sessions uncomfortable; This is the most natural mouse that I've held

Thick cable which is stiff - this may seem nit picky, but I game on a hard gaming mouspad that requires very little force input to move the mouse; When the cable is bent in a smaller radius, I can feel it at the mouse.

I really wanted to like this mouse, and it is alright, I guess. However, the last two Logitech mice I've had have not been of nearly as good quality as their older products. The scroll-wheel on this one was not as firm as I would like, and after several months it has started occasionally scrolling...

Highly recommend for anyone wanting a top end gaming mouse with the convenience of wireless.

Top end sensor; very light left and right click; delay isn't even noticeable; perfect shape for my hand; alright lighting

Sensor rattle; it's a little loud but when you're actually using it it's not terrible and doesn't affect my gameplay at all; the right click is starting to have an issue where its very hard to press every now and then; it feels like a piece of plastic is stuck in the switch or something.

Its just perfect. I love the texture on the sides because it doesn't get oily or slippery due to sweat or oily hand. Its amazing performance wise as well.

This mouse has a fantastic shape and feel, with gold buttons and a light construction but mine has just now failed. The tracking is steppy and glitchy now making FPS games unplayable. The triggers seem to have lost a lot of the clickiness and depth making for a lot of misclicks.

Don't buy this, go for g102 or zowie. U can't do micro adjustment in game if u r a fps, it has a huge bump on the back which help u to rest ur palm but this back bump will block u from doing micro adjustment using finger tip.

Mouse is precise and comfortable to hold. Light to pick up and the only problem i found was that the lift off distance was very small ( you need very plane surface and i recommend using Steelseries qck mass or qck heavy).

The G403 is such an amazing choice for those who want a comfortable gaming mouse that is just the right speed and as well with the weight. You can remove the 5g weight or add to best fit your style of mouse.

After much deliberation & research I finally settled on the G403 Wireless from Logitech. This is an excellent gaming mouse. Buttery smooth, accurate, good size, rechargeable via USB (also works plugged in over USB, so no worries about battery failure).

Decent mouse, lots of customizable dpi settings and feels good in your hand.
