There was a time when the concept of a “gamer mouse” embraced multiple buttons, RGB lighting, and even tiny weights to tweak its balance. These days, the trend has flipped: the single goal is to make them lighter and lighter. YouTuber Optimum offers the Zeromouse V35, a modkit that weighs just 26 grams in wireless mode, but he recently revisited the design and managed to shave it down to less than 16 grams, ditching the scroll wheel and side buttons. Does it make sense for the online gamer…?

Just as a mechanical keyboard can accept alternative switches and other advanced mods—such as lubrication or replacing stabilizers—gaming mice are following a similar path with special sensors, more sensitive switches, and, of course, a general loss of weight. For many players, it's an obvious optimization: a lightweight mouse moves faster and with less inertia in high-intensity matches, but the question remains: What's the limit? Where is the line between practical and absurd?.

Zeromouse, a cloud between the fingers

Optimum tried to answer those questions in a very particular way. The YouTuber sells a modkit called Zeromouse V35, which takes the guts of the Razer Viper V2 Pro (58 grams, 120 euros) and turns it into a 26-gram mouse. Recently, he went further and modified that design to make it compatible with the PCB of the Zaunkoenig M3K, an ultra-premium 24-gram mouse available only in very limited numbers.

The result is a small monster that doesn't quite exceed 16 grams, although that requires removing the scroll wheel, side buttons, and the DPI selector found on other mice. In Optimum's own words, it's the mouse equivalent of a Formula 1. What's most impressive is that it could still shed two or three more grams, but that would force the user to make certain compromises and could hurt its “grip”, so to speak.

I've put more sugar in my tea before...

The second half of the video is essentially a commercial for the Zeromouse V35, but some of its technical details are still surprising, such as printing in Nylon 12 via SLS (Selective Laser Sintering), which doesn't require traditional supports. To wrap up, lightweight mice are no silver bullet, and Optimum is the first to admit it. The key is to practice, learn, lose, and repeat the cycle.
