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 use this for gaming, and I haven't experienced any delay. I moved mice from a G502 to the G403 and the lack of cord is a real boon to my mouse accuracy. I would actually recommend this mouse over the G502 for a more consistent feel.

Comfortable Grip; Awesome Tracking; Great Battery

Slightly smaller than I would like; The back portion could be more elevated

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...

Without sounding like a shill, the mouse perfect. Logitech already host a number of the top mice in the world (the G502, G900 and MX master) and the G403 is better than even these. At near 90g its a good weight, the shape is comfortable for palm and claw grip (I don't know about fingertip however it...

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.

From the number of thumb buttons on the side to the number of LED colors on the palm rest, gaming mice have never been more versatile. Do we really need another one? Logitech's answer is an enthusiastic "yes," as made evident by its two brand-new mice: the G403 Prodigy ($70) and the G403 Prodigy...

Comfortable grip; Intuitive software; Excellent fidelity on wireless variant

Derivative design; Unsatisfying thumb buttons; No more beginner-friendly than competing mice

As a general six-button gaming mouse, the G403 delivers, but Logitech offers better (and better-value) mice for serious gamers in its own line.

Attractive design; Adjustable weight system; Lift-distance wizard; Stores five DPI settings onboard; Supports game-specific profiles

Realistically; only two buttons to program; No DPI-shift toggle or thumb rest; No sleep mode; Pricey versus older; better Logitech mice
