Like the rest of Razers equipment the Taipan utilizes the Synapse software to customize the mouse even further.

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 Side buttons can irritate ring finger
The ambidextrous extra buttons on the side may rub against the ring or pinkie fingers.
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.
