Surface

The surface is smooth but a bit textured, and it is matte UV coated. Both main buttons are made out of PBT plastic, which, unlike ABS, does not lose its texture (it doesn't get shiny) and color even after years of heavy use. The mouse feels nice in the hand overall, but this is as intuitive as it gets, of course, so what I like you may dislike. From an objective point of view, it should be good with most users.


Both sides of the mouse have textured silicone grips. This is a feature that could have been done better in my opinion. They can get quite slippery with sweaty hands, which is a bit of a letdown because they should be grippy instead. I am not saying that this will affect all users, of course, as everyone is different. However, if your hands start sweating easily after a few minutes of playing, and you don't like DIY solutions to problems like these, I don't suggest choosing this mouse.

Build Quality

No squeaks, no creaks. The build quality is excellent—quality control was on point here as well. Only the CPI-changer buttons make a small rattling noise when I shake the mouse very very hard, which should absolutely not be an issue during normal use. It is also sturdy and does not feel like it is going to fall apart in your hands when you grip on it firmly.

Weight

The stock weight is around 102 grams with a few centimeters of cable, so it's just like the MM520 in this aspect as well. However, the MM530 is significantly bigger, and while the MM520 felt heavy and sluggish in my hands, this one feels pretty good out of the box. There is a built-in weight you can remove after opening up the mouse.


You can do so by peeling off the rear feet to then remove the screws. Be sure to open it gently because the top and bottom PCBs are connected with a ribbon cable. If you are too harsh with the opening, there is a chance you will rip it off the soldering.


Now, by removing the weight, you can shave off around 7 grams, making the mouse roughly 96 grams including a few centimeters of cable. This is reasonable for the size, but in my opinion, it could have been made lighter still.
