Buttons, Scroll Wheel

Logitech's buttons were always renowned among gaming mouse enthusiasts as they are generally really good. Logitech focuses on this aspect a lot, and they constantly improve their buttons—sometimes, there are some errors here and there though, mainly with the scroll wheels and middle buttons, but thankfully, that is not the case here.


Both main buttons are astonishingly good; they have zero unnecessary travel and are fairly light, but spammable and very tactile. They use Omron D2FC-F-K switches that are rated for 50 million clicks.


The scroll wheel is great; its steps are well defined, but quite easy to scroll through, so this may be ideal for both gaming and browsing. The encoder is manufactured by TTC.


The middle mouse button is a tactile switch, and I could find no branding here. This one is harder to press than any other buttons on the mouse, but it's not overly stiff, so it may be comfortable for long sessions as well. I would generally prefer something a tad lighter, like on the SteelSeries Rival 600, for example, but that is up to personal preference.


As for the side buttons, they are pretty unique. They are modular, which means you can choose which ones to use and which ones to simply place a cover on. Both the buttons and the covers are held in place by two-two magnets on each side. Lefties rejoice, finally a truly ambidextrous gaming mouse that lets you remove the side buttons you don't need! Now, for their clicks, they too feel really nice; there is hardly any pre or post travel and they are very tactile and generally feels nice to click. The wired G Pro and its lower-cost iterations received a lot of criticism for their subpar side buttons, but thankfully, Logitech learned from their past mistakes.

There is also a CPI cycle button on the underside of the mouse, but as far as I could tell, it cannot be rebound to another function. While the PRO Wireless may not have the absolute best clicks on the market, it is very close, and that is kind of up to personal preference as well.

I made a video in order to demonstrate how the buttons sound:

Cable

Ironically, a wireless mouse has one of the best stock cables I have ever seen or used. The one on the PRO is just amazing—very thin, light, and flexible. The micro USB connector is firmly in place once attached, so there is pretty much no chance of it dislodging by accident.

Mouse Feet

Moving on to the mouse feet, this is pretty much the only part of the mouse I was dissatisfied with. Logitech's stock feet seem to have a lot of friction, and they tend not to really break in after days or weeks of use. It is no different with the PRO, unfortunately. Their glide is even and pretty smooth, but they have quite a resistance to them.

The three bottom feet surround a lid that is held in place by two fairly strong magnets. Once this lid is removed, a spot for the wireless receiver while charging the mouse is revealed. If you aim for the lowest possible weight, you can lose a few grams by not putting this lid on.

Disassembling

I would highly advise against disassembling the PRO as that will most likely destroy your mouse feet, and there are currently no aftermarket ones available. This mouse also has a very advanced construction, which can make re-assembly quite challenging and frustrating. If you are still convinced you have to dismantle the mouse, you can do so by removing seven small screws from underneath the mouse feet, but there are many more screws inside the mouse itself if your goal is to take it apart completely.
