Surface and Materials

As previously mentioned, there are a total of four variations of this pointer device—you can take a look at the matte black model in most of the photos in this review.


The reason behind having both glossy and matte variants is because a lot of users actually prefer a shiny surface for their mouse, especially those with very dry hands. For them, the lacquered-like finish provides more grip than a standard matte paint.


There is no difference between the side and top covers in terms of surface treatment, meaning it's the same coating everywhere on the main holding areas. There isn't much to say about the glossy finish as it is pretty much the same everywhere, but the matte variant is more interesting in terms of touch. It's an almost rough, grippy surface, and since the mouse is so light, it tends to provide more than enough traction to keep your grip. My hands are known to be quite sweaty, but even after hours of gaming, I never lost control of the mouse.


The scroll wheel's cover is made out of rubber and features a very good slotted texture, making accidental slips nearly impossible. Both the side and CPI buttons have a glossy finish on all Model O mice. As for the holes: they sure don't make the mouse very appealing visually for most people, but do the job very well. You can't really feel them; they won't leave marks on your hands, and I never felt any discomfort while using the O or any other mouse with a similar design.

Build Quality

I only came across one issue while checking on the build quality: the sides can actually flex a bit if you press on them with great force. Now, I use a claw grip with low in-game sensitivity, which has me press on the sides rather hard sometimes, but I definitely didn't notice any flex during regular use. If you have very strong hands and grip your mouse like a vice, it's best you skip the Model O. Else, it's just perfect as there is no rattling, creaking, or squeaking of any sort, and the mouse feet are aligned well. This product is very well put together, but being extremely lightweight, it obviously has the downside of being a tad more fragile.

Weight

Weight is one of the main selling points of the mouse as many enthusiasts pick the lightest rodent. For its size, the Model O is truly amazing, being only 67 grams for the matte and 68 grams for the glossy versions according to itsspecs. In reality, it measured in at an additional gram to each, but I've added the few centimeters of cable you're gonna move with the mouse anyways. There are many advantages to a lightweight mouse, but weight is still a personal preference. 67 grams won't nearly tire out your hand as much as a mouse twice as heavy.
