Surface and Materials

The top part (including the Logitech G logo at the back) has a glossy finish with an absolutely stunning pearlescent, fading finish called Nightfall. The front end is silvery and transitions into deep black towards the
end. Even though it looks absolutely fantastic, I personally don't really like its glossiness. My hands are rather sweaty, so this surface can get slippery easily. Thankfully, the sides pretty much compensate for this, which I will touch on more a bit later. The scroll wheel is basically the same as on the predecessors, so its entire surface is made out of smooth rubber. All buttons on the middle plate have a matte black finish and very subtle glossy markings.


The side panels feature a rugged, slightly textured matte finish that doesn't feel like it's rubberized, but it definitely provides a ton of grip. It's among the best materials on a mouse I've yet had the chance to try, and in my opinion, it would be great on top as well.

Lastly, the side buttons have a semi-matte finish with very subtle arrow markings that look very sleek.

Build Quality

The original MX518 was as solid as a rock, which thankfully didn't change with the G-updated version. It doesn't emit any rattly, creaky, or squeaky sounds, nor could I find any misalignments anywhere. It's well built and sturdy, without anything for me to nitpick on.

Weight

The G MX518 weighs about 103 grams with a bit of cable, which means it has a fair weight for its size. It actually feels lighter than it is, but just like I've written many times before, a lighter mouse is generally better for your wrists in the long run. This mouse is fairly well balanced, though it feels a tad nose-heavy if you pick it up at exactly the middle.
