Buttons, Scroll Wheel

Main buttons feel very nice; they are tactile, snappy, and nicely spammable. They have no unnecessary pre-travel, but there's a minor amount of post-travel after actuation on my unit. They use Omron D2FC-F-K switches rated for 50 million clicks. Endgame Gear also claims that these switches are pre-selected, so both have the exact same click tension. Bear in mind that these switches come out of the factory with a nominal 75 gf actuation force, but have a ±15 gf tolerance. This means most it's a lottery: when there's no pre-selection, you may get 60 gf on the left click and 90 gf on the right, for example, which feels horrible, of course. I have two copies of the XM1, and both of have really nice and even clicks, so Endgame Gear really did a good job here.


Scrolling is very tactile, and I think I can safely call it a bit too tight for my taste, but this is mostly up to personal preference. It uses a 9 mm high Alps scroll wheel encoder, which is considered among the best in the market. The XM1 has a rather small wheel, though, which makes scrolling feel a tad heavier than with a large scroller.


Moving on to the middle click, it's a bit stiff for my taste. It's way harder to click than the main buttons, so it can be tiring to use in the long run. However, it pretty much eliminates chances of accidental clicks while scrolling. The switch is a standard-height EVQP0-style square switch.


Side buttons have an average amount of travel and a medium-light tension. They could be a tad more tactile, but are overall still really good, and can be spammed easily, too. Later batches have more tactile side buttons due to a small internal design change. Their switches are laying TTC models with deep red plungers.


Lastly, there's a button at the bottom of the mouse that controls the CPI levels and polling rates. It operates with a small tactile switch.

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

Mouse Feet

There are a total of four medium-sized mouse feet at the bottom of the mouse. These feet are really good, better than most other manufacturers provide. They are made out of over 99.5% pure PTFE. Their glide hardly has any friction and is smooth; however, the skates could have slightly rounder contact edges for a truly perfect glide quality. Unfortunately, no replacement sets are included, which is a bit of a letdown.

Cable

While paracord cables are becoming a fad among not only enthusiasts and modders, but manufacturers, too, Endgame Gear didn't jump on this bandwagon. They went with a standard rubber cable instead—one that's really flexible compared to about 99% of the competition, so while it's not as slinky as a custom "paracable", it's still really good and doesn't have much drag resistance. At 1.8 meters (5.9 ft), it should be long enough for most users.

Disassembling

Disassembling this mouse is easy, but you most probably have to sacrifice the really good mouse feet in order to do so. There are a total of four screws beneath these which have to be removed in order to disassemble the XM1. Once removed, the top cover can simply be popped off. As there's only a single PCB inside, the internal structure of the mouse is very user-friendly.
