Specs
Ranked in these QuestionsQuestion Ranking
Pros
Pro Great for palm grip
The Logitech G400 gaming mouse was clearly designed specifically for palm grip.
Pro Thumb-rest
There is a built in ergonomic thumb rest so users can rest there thumb instead of constantly gripping.
Pro Comfortable side button placement
The two side buttons are located in an easy to reach, unobtrusive position.
Pro A true successor to the legendary MX518
The Logitech G400 gaming mouse is based off of MX518. It has a few minor incremental improvements that don't change what made the original so great.
Pro Accurate 3600 CPI optical sensor
The mouse has an accurate Avago ADNS-3095 optical 3600 CPI sensor. No angle snapping, no acceleration, no prediction.
Pro Quick-access CPI shift
Above and below the scroll-wheel there are buttons that allow increasing and decreasing between 400 and 3600 CPI on the fly.
Pro Good build quality
High quality rubberized coating is used among other materials to give a quality product feel.
Pro CPI shift
CPI can be changed from 400 CPI up to 3600 CPI without having to interrupt workflow.
Pro Excellent sensor
The G303, along with the Logitech G502 and G900 and the Corsair M65 PRO RGB, has the single best sensor on the market, the Pixart PMW3366. This sensor has no acceleration or angle snapping that can't be disabled and has a native DPI of 12,000.
Pro Compact size gaming mouse
People with small hands needn't look at mice like the Corsair M65 gaming mouse and despair. The G303 gaming mouse has a solution. It's about the size of the $5 USB mice that are often bundled with desktop computers, but it has most of the features of a full-size gaming mouse.
Pro Comfortable
Logitech G303 is very comfortable if you have medium to small hands, and if you are using your mouse with claw or fingertip grip.
Pro Accessible price
The G303 gaming mouse has an MSRP of $49.99, but it goes on sale rather frequently for as low as $24.99. Compared to high-end gaming mice like the Rival 700 and the G502, that's quite a steal.
Pro RGB lighting
It glows. You can change the colors. There isn't much more to say, except that it will fit in with basically any setup that uses black devices with colored lights.
Cons
Con Scroll wheel is shallow and loose
Like the versions before it, the scroll wheel feels shallow and loose.
Con Lift off distance too high
The lift off distance is too high for this device but it can be fixed by using the tape trick.
Con Superseded by Logitech G400s
This unit is no longer in production though some units can still be found on Amazon and Ebay.
Con Build quality not the best
Scrolling wheel sometimes makes cranking noises while you are scrolling through it. If you tighten the mouse from the sides, the cheap plastic will make a noise.
Con A minimum selection of buttons
The Logitech G303 only has one controllable button on the top, two buttons on the side and a programmable mousewheel. The mouse offers six different buttons if you include left- and right-click.
