FPS Ergonomic - Logitech G403 Review

Recently, using my G900 Chaos Spectrum, I noticed a new phenomenon - my ring and pinky fingers were cramping up. I was intrigued; my hands are usually quite supple and I was wondering why this was happening. It turns out that the ambidextrous shape of the G900 was the culprit of this pain. Because the walls of the mouse are curved inwards on both sides of the mouse to accommodate both lefties and righties, your ring and pinky fingers must curl up in order to be above the mousemat.

However, I found a mouse that could serve all my needs and more, at a smaller price. Enter the Logitech G403 Hero. There are a few key things that set this mouse apart from other mice: shape, build quality, and feel. We're going to explore them all, and at the end of this review I think you will be convinced this is a great mouse too - especially given its relatively low price of $50.

Summary and Specs at the bottom!

First, the shape. Shape is absolutely an under-appreciated aspect of gaming mice, and mice in general. It seems that unless you have a carpal tunnel, no one is going to pay attention to the shape of the mouse. Now, I'm not saying you should go out and buy the $100 MX Vertical Mouse. All I'm saying is, something that I really appreciate about the G403 is the ergonomics. It takes knowing the pain of attempting to palm grip an ambidextrous mouse to understand.

The shape of the G403 is reminiscent of the acclaimed ergonomics of the Razer Deathadder. There is a hump in the perfect spot to have a scrumptious palm grip, but is not so far back as to prevent a great claw grip as well. My ring and pinky finger now feel nicely rested, and, this might be a result of my thin fingers, but I have more control over the G403 than the G900. I can use this mouse for the whole day and my hand feels just fine afterward.

Secondly, build quality. All fifty dollars you spend are devoted towards the superior materials in this mouse. The back is smooth plastic with a matte coating that keeps cool during even strenuous and long gaming sessions. All the switches on the mouse, even the DPI button, are top-notch Omron switches. This makes them very tactile and responsive, allowing you to click not only accurately but very quickly as well. The whole mouse is light but very durable. There is fully programmable RGB lighting in the massive G logo as well as an aesthetically pleasing line through the middle of the scroll wheel.

And this brings me into the last tenet of this mouse, feel. The whole thing feels quite premium - the rubber sides are grippy yet smooth and the back is silky. Additionally, the scroll wheel is superb. Although you can't switch between scroll and flywheel, the wheel included is a great combo of both. The scroll action is velvety, but still has defined, but muted bumps. It's great for both scrubbing and accuracy. At 90 grams (without 10gram weight), this mouse is quite light and exceedingly easy to control. Although not in the "ultralight" class, which usually belongs to mice 75 grams and under, this mouse is definitely lighter and therefore more controllable than some of its competitors such as the Razer Basilisk V1 or V2, Corsair Glaive, and Logitech G502.


Overall, this is a well-crafted, reliable, and ergonomic mouse. It has everything you need in an FPS mouse, and more, such as tasteful RGB and a chic matte black finish. Coming in at a comparably low $50, there is very little reason not to buy this if you are looking for a solid, ergonomic FPS mouse.
