As a rule of thumb, heavy mice are best for wrist flicking while lighter mice are best for tracking because of the lower inertia required. Heavier mice can be more stable for aiming but due to the heavier weight the mouse is harder to stop so, it can feel a bit slow when performing large mouse flicks. Overall, a lightweight mouse has the upper-hand over heavier ones because you can lower the in-game sensitivity and still be as quick as a heavier mouse on a higher sensitivity.

The GameSir GM500 (pictured) is a nice example of lightweight mouse. It's a honeycomb type computer mouse but, instead of honeycomb perforations the GameSir GM500 has small triangular perforations arranged in a circular pattern across the top and backside of the hump. Perforations extend also to the sides with the right side being entirely perforated, while the left side is only half perforated to accommodate two left side buttons, which are clicky and made of plastic.


The bottom of the GameSir GM500 mouse is entirely perforated too. So much so, that you can see through to the other side. The total weight, including the cable is 103 grams. Without the cable, the GM500 mouse weighs 74 grams, which is very light, although not as excessively light as some ultralight honeycomb mice that weight 40 grams and feel like holding a feather. The GameSir GM500 measures 12cm long, 7cm wide and 4.5cm high so, it has a pretty steep hump. The mouse works well in palm, claw and fingertip grip and fits comfortably small/medium hands.


The GameSir GM500 mouse weight is good enough for work related applications other than gaming. Weight isn't everything, although it pairs well when gaming in low sensitivity. You can easily drag the mouse across a large area without much effort, which is a huge advantage in first person shooter games.
The GM500 left and right click buttons are not perforated and have a wide surface area to comfortably accommodate the index and middle fingers. The left and right click buttons are separated by a centre divider that integrates the scroll wheel that has a smooth silent operation. The scroll wheel is rubberized and textured with the same circular-split triangle pattern as the cutout perforations on the shell of the mouse. 


The scroll wheel integrates a centre push button and leds, which light up the side rings of the scroll wheel. Behind the scroll wheel, there is a small plastic dpi button which is located far enough so, you don't accidentally press it when scrolling. The dpi button lets you cycle between 7 dpi levels (400 dpi, 800 dpi, 1600 dpi, 2400 dpi, 3200 dpi, 6400 dpi and 12,000 dpi). When selecting dpi, the mouse led lighting flashes a different color for each dpi (refer to the user guide for more info).

Three other settings you can adjust directly from the GameSir GM500 are the lighting effect, brightness and the polling rate. By pressing the scroll wheel and dpi button at the same time, you can adjust polling rate from 125Hz, 250Hz, 500Hz and 1000Hz. To change lighting effects, you press the side (forward) button at the same time. 


You have three modes to choose from color changing, single solid color (7 colors) and single breathing color. To change the brightness level, you press the dpi and side (back) button at the same time. You can adjust from high, medium and low, although the brightness levels have a similar intensity so, the adjustment is very subtle. There only 2 led lighting zones: the scroll wheel and the Gamesir logo on the back.

The GameSir GM500 mouse is connected to a non-detachable 1.6 meters long cable with a shoelace-style fabric braided sheath, which is reinforced internally with a bendy wire that feels like memory wire. The cable isn't stiff though, which is nice because it creates less cable resistance when dragging the mouse around; hence you won't need to use a mouse cable bungee. The cable is attached to a USB-A connector with a rubber plug that has the Gamesir logo branded on it.


The GameSir GM500 has solid performance to match the sleak looks. It uses a 12,000 dpi optical sensor (PixArt PMW 3360) which is a top performing mouse sensor capable of 250 IPS (inches per second). This means, the mouse doesn't stutter or glitch when swiping the mouse really fast, although you need a mousepad that provides good friction to control the mouse more accurately. The GameSir GM500 ships with three stickers, as well as an adjustable rubber strap to tie the cable neatly for transportation. You can buy the GM500 from Gamesir.
