I really like the x108. Before I bought the x108 I had bought the atom 68 which I also think is an amazing keyboard... which is why I ended up buying the x108 to use for work.
The x108 has the same great switches and I really like the light feel and dampened sound and, even though it isn't necessary for me, I like that these keyboards have NKRO with the capacitive switches. One nice aspect of both of the Niz Plum keyboards I have is that even though they have NKRO they still work fine outside of windows without having to switch to 6KRO like my other keyboard do.
One place where the x108 differs from the Atom 68 is with the keycaps, and this is both a good and a bad thing. The good part is that the x108 keycaps are nice PBT doubleshot keycaps so the lettering is incredibly sharp and will never fade over time. The bad part is that the keycaps on the x108 are thinner than the Atom 68 keycaps (which are thick PBT but not doubleshot). This leads to the x108 having a little less premium feel and sound than the Atom 68. It's not a huge difference but definitely one that I noticed after having used the Atom 68 for a few months prior.
Some other aspects that I really like about the x108:
-amazing key feel... it takes a little time to get used to the lightness of the 30g switches but they feel and sound amazing (like quiet, muffled popcorn popping).
-very quiet... you won't be bugging anyone while typing on this keyboard
-dedicated volume buttons above the number pad
-a number pad... super helpful for a work keyboard
-dedicated f-keys... also super helpful for work
-adjustable key height activation thanks to the capacitive switches
-not backlit (on the version that I bought anyways) ...sometimes I just don't want a backlit keybard... especially on a keyboard this nice.
-I haven't used the programmability yet but this is also a plus.
-I really like the clean white look of the x108 (and the Atom 68). Some people think that the white makes these keyboards look dated but I personally don't see that and I think they look very clean and no-nonsense unlike 99% of the other keyboards out there. I'd much rather have this clean look than a backlit keyboard with weird legends and metal knobs, and edgy decals, etc...
a couple of minor issues:
-the spacebar sticks up higher than the other keys by a little bit and shows a slightly larger gap between the bottom of the spacebar and the keyboard surround than the other keys (I'm guessing this is because it uses the same spacebar as the Atom 68 and maybe it wasn't intended for this keyboard originally?).
-The indicator lights for capslock, numlock, and scroll lock aren't isolated and just shine up through the keyboard so that you can see the lights illuminating the surrounding keys and frame. It just makes this really nice keyboard look a little cheaper than it should with all of the light leaking through. You can alleviate 90% of this issue by lowering the light brightness all the way down (which looks better anyways so it's not a big deal).
Overall, I really like using this keyboard daily for work and it's even great for gaming with the light key activation, adjustable height actuation, and NKRO.
I think that the x108 is a great purchase and feels really unique compared to any other keyboard I've ever used.
