Surface and Materials

Materials on the MM830 are great to say the least. Just like some previous models, such as the MM530 and MM520, the MM830 features PBT main buttons, which are a different type of plastic than the rest of the shell. It's a slightly coarser, grippier material, which you will instantly notice by touching the surface, but very durable, and even if it wears out a little, it doesn't get shiny, like standard ABS plastic. The rest of the body feels very similar to the main buttons, but is made out of ABS and coated to feel like PBT. I'm pretty sure this is due to PBT being way more expensive, and it's a lot heavier, too.


Moving on to the left side panel, it features a smooth, soft rubber material on the thumb rest and side buttons. This feels nice and tacky, and should provide enough grip to avoid losing control in tense situations. The OLED screen's cover on the front is of course made out of a glossy, shiny material. The scroll wheel has a textured rubber finish, so no accidental slips should occur while using it. The CPI-changer has a glossy black coating.

Build Quality

As for the build quality, the MM830 is rock solid. There is literally nothing I can nitpick on; it's just perfect. Everything is aligned well, nothing rattles, squeaks or creaks. Way to go!

Weight

We've arrived at the point I really don't understand about the MasterMouse MM830. If you remember the MM520 and MM530 models, they had built-in weights, which the community really disliked and raised their voices against—mostly because you had to disassemble the mouse to get these out, which lead to losing the warranty. Then, Cooler Master re-released the MM530 without the weight plate, naming it the MM531. Now, a few months later, the MM830 arrived, weighing a staggering 128 grams with a few centimeters of cable. I initially thought the mouse is so heavy because of the OLED screen, robust shell, and thick PBT main buttons, but that is not the case as there are three small weight plates screwed into the inner shell for 16 grams in total. This is something I just don't get—it is outrageous and not very clever in general as the mouse is already heavy without these. Now, shape and weight are up to personal preference, but the latter should generally be low for the sake of long-term comfort and your wrists.
