With the wired GM41, the verdict was pretty straightforward: good mouse, but the ultra-stiff cable kills it. The easiest way to solve this is by getting rid of the cable, and that's exactly what MSI did with the Clutch GM41 Lightweight Wireless.

As a result, the strengths of the GM41 finally come into play on the Wireless: 75 g for a medium to large mouse without holes and driven by an internal battery is indeed appreciably light. Build quality turned out to be solid as well on my copy: no rattle, no creaking, and activating the side buttons is only possible by squeezing the sides with excessive force. The pure PTFE mouse feet complement this further, which glide very nicely indeed. The main buttons are outfitted with the recently introduced Omron D2FC-F-K (60 M) switches and provide a distinctively snappy and highly satisfying click feel, and on the side buttons, pre and post-travel is minimal. The scroll wheel is pleasantly low on noise, but tactility leaves room for improvement. To help with grip, the sides are made out of hardened rubber with a bumpy texture. In short, MSI did great on the physical side of things with the GM41 Wireless.

As far as sensor performance goes, things are looking good, too. Much like on many other PAW3370 implementations, motion delay is higher at the onset of motion, but USB polling is perfectly stable across the board, and CPI deviation minimal. Wireless delay was somewhat difficult to determine, but it appears to be around 1–1.5 ms, which is up there with the best. Curiously, adjusting CPI steps in increments of 50 isn't possible in the software despite the 3370 supporting it. In the software, a novel feature called "Motion Sync" can be enabled, which has been seen exclusively on several Razer mice so far. My testing shows that Motion Sync indeed does what it is supposed to; i.e., tighten SPI timing, resulting in more consistent tracking. Even though having this feature enabled goes hand in hand with higher power consumption, I found it to be a worthy trade-off. Speaking of which, with Motion Sync enabled, polling rate set to 1000 Hz, and no RGB lighting, I estimate battery life to be around 50 hours, which is pretty good considering the battery in the GM41 Wireless isn't the largest. The charging process is eased by the inclusion of a charging dock, which is a novelty in the $100 and under price bracket. With the dock, one can simply charge the GM41 Wireless over night without having to plug the cable in. This is highly convenient since the regular Micro-USB connection doesn't charge all that fast and actually plugging in it can be finicky. In general, I would advise against using the GM41 Wireless in wired mode as the charging cable is incredibly stiff, and, for inexplicable reasons, motion delay is absurdly high when plugged in. Enabling Motion Sync helps a bit in this regard, but as a whole, using the GM41 Wireless, well, wirelessly is definitely preferable. Granted, wired operation on a wireless mouse being worthwhile in terms of motion delay and cable stiffness is typically only important if one has forgotten to charge the mouse for days, which the charging dock makes much less likely. Another strong point of the GM41 Wireless is click latency, which is around 3 ms.

In the interest of battery life, RGB lighting has been kept at a minimum on the GM41 Wireless. If desired, the lighting can be configured within MSI Dragon Center, which is MSI's unified software suite. While nowhere near as horrible as ASUS Armoury Crate or Corsair iCUE, Dragon Center does eat up quite a few resources and, more annoyingly, resets any non-default ICC profiles upon any system restart. On the bright side, a battery life indicator with single-digit precision is included, which helps with gauging when the mouse is in need of charging. I also liked that firmware updates were applied over 2.4 GHz without issue, which is something many manufacturers seem to be struggling with.

All in all, I really enjoyed my time with the Clutch GM41 Lightweight Wireless. The included charging dock is a huge plus, and although an asking price of $95 doesn't put the GM41 Wireless into the budget bracket, value for money is no doubt excellent. This becomes even more evident when looking at the competition. The Razer Viper Ultimate too comes with a charging dock, alongside slightly better performance, optical switches for the main buttons, and similar weight and build quality, but costs $149.99. The Logitech G Pro Wireless goes for $149.99 as well, has excellent performance, low click latency, similar weight, and strong battery life, but lacks the charging dock. The ASUS ROG Pugio II not only lacks the charging dock, but also a wireless extender and comes with great performance, hot-swappable main button switches, and slightly higher weight, for $99.99. The SteelSeries Aerox 3 Wireless has very good performance, low weight, but lots of holes, and poor battery life with RGB enabled, for $99.99. Lastly, the Glorious Model O Wireless is closest to the GM41 Wireless in terms of shape, has great performance, low weight, plenty of holes, and both a wireless extender and flexible charging cable included, for $79.99. To sum it up, the MSI Clutch GM41 Lightweight Wireless is a great mouse with only minor flaws, and thus earns our Recommended award.
