Introduction

unnamed file 475

Established in 1986, MSI is a computer hardware company based in Taiwan. Aside from being wireless, the Clutch GM41 Lightweight Wireless is very similar to its wired sibling: A lightweight construction of 75 g without externally visible holes, Omron switches rated for 60 million clicks for the main buttons, and pure PTFE mouse feet. Instead of PixArt’s PMW3389, the PAW3370 capable of up to 20,000 CPI is used. MSI cites a maximum battery life of up to 80 hours. Basic RGB lighting is included and can be customized through MSI Dragon Center, which also provides all the other usual options. A novelty in this price bracket is the inclusion of a charging dock, which eases the charging process.

Packaging, Weight, Cable, and Feet

Packaging

Aside from the mouse, one finds a charging dock, charging cable (USB Type-A to Micro-USB), and quick start guide in the box.

Weight

unnamed file 478

My scale shows around 75 g (+/- 1 g), which is almost exactly in line with the weight cited by MSI. An excellent weight, especially when considering the fact that the GM41 is a medium to large mouse and that it is achieved without resorting to the hole treatment. By comparison, the similarly sized Razer Viper Ultimate and Logitech G Pro Wireless clock in at 74 g and 80 g respectively.

Cable

The Clutch GM41 Lightweight Wireless comes with a braided charging cable (USB Type-A to Micro-USB). Though not quite as stiff as the cable of the wired GM41, this charging cable too is of the ultra-stiff variety. I consider it unusably stiff for gaming. Its measured length is 1.95 m.

The charging cable can also be used to connect the included charging dock, which doubles as a wireless extender. Ergonomically, the docking station leaves something to be desired, as plugging the charging cable in is just as difficult as unplugging the wireless dongle.

Feet

The feet on the Clutch GM41 Lightweight Wireless are white-dyed pure PTFE (Teflon) feet with slightly rounded edges. Glide is excellent. The ring around the sensor ensures CPI stays consistent upon applying vertical pressure.

Shape

The GM41 Wireless has a somewhat unique shape. It is a rather long, yet low-profile mouse with a centered hump that gradually slopes down towards both ends. Whereas the front doesn’t flare out by much, the back has a rear flare not unlike that of the Sensei or XM1. Though the curvature isn’t exactly the same, it is similar in that it helps with “locking” the back of the palm into position when claw gripping. As a result, stability is great despite the lack of palm support. The back flare also helps in keeping the thumb in place, but can be irritating for the pinky depending on how one grips the mouse. The main buttons feature very subtle comfort grooves, along with small ridges towards the sides, which seem to be there for aesthetic purposes. Overall, a design that is quite unusual, but works well in practice.

As for grip styles, I’d say the Clutch GM41 Lightweight Wireless is mostly suited for claw grip. Fingertip grip may be possible as the main buttons are quite long, so even when gripping the mouse towards the back, the main buttons are still within reach. It’s a medium to large, yet low-profile mouse, which should make it suitable for most hand sizes. For reference, my hands are 19 cm long and 10 cm wide, and I found the Clutch GM41 Lightweight Wireless very comfortable in claw grip.

Dimensions

This table includes the dimensions of the MSI Clutch GM41 Lightweight Wireless and several other ambidextrous mice. “Front height” denotes the distance between the base and main buttons. Measurements with two decimals have been taken with a caliper, while those with one decimal have been taken with a ruler.

Build Quality

Overall build quality is very solid. There is no rattle when shaking the mouse. When applying lateral pressure, no creaking or flexing of the shell can be observed. Activating the side buttons by squeezing the sides requires excessive force. Lastly, no accidental clicks occur when slamming down the mouse.

Buttons

Main buttons on the Clutch GM41 Lightweight Wireless are very good. Pre-travel is low and post-travel moderate, resulting in a firm and highly satisfying button response. However, when tapping, the right button emits a rather loud “thunk” sound. While these buttons are visually separated from the shell, button wiggle is minimal. Button stiffness is medium to light. A set of Omron D2FC-F-K (60 M) (China) switches with an actuation force of 60-65 gf is used.

Side buttons are very good. Pre and post-travel are minimal, resulting in a snappy button response, but the buttons don’t sit entirely firm, leading to a somewhat flimsy feel. The pressure point is even across the entirety of these. Button size and placement are good as actuation is possible rather easily by rolling one’s thumb across, though depending on one’s grip, the forward placement of the buttons may not be liked. A pair of Huano switches (blue plunger) is used here.

At the bottom of the mouse is a single button for cycling through the set CPI levels. Its click feel is good. A seemingly unbranded tactile switch is used for this one. Also found at the bottom is a slider that switches between on and off state. This slider has a small indentation, which makes it very convenient to operate.

Scroll Wheel

The scroll wheel is very good. Noise levels are appreciably low when scrolling in either direction, but the steps themselves lack separation, resulting in just average tactility. The encoder comes from CF (ChangFeng) and has a height of 11.5 mm. The middle (scroll wheel) click requires medium force for actuation. A seemingly unbranded tactile switch is used.

Coating

The Clutch GM41 Lightweight Wireless has a fairly smooth matte coating on top and a bumpy rubber texture that is oddly soft to the touch on the sides. Grip is fine on either, and neither surface attracts fingerprints, dirt, or the likes too much. They are easy to clean, and there are no signs of wear left after doing so. All in all, excellent materials.
