The Corsair K100 is a full-sized keyboard that takes up a significant amount of room on your desk, but you can remove the wrist rest to save space. However, if you prefer a modular keyboard where you can remove the numpad to use it in TKL mode, then look into the Mountain Everest Max.
Update 07/22/2021: While the majority of the keys on the board are made of PBT, the macro keys and the extra keycaps in the box are actually ABS keycaps. We updated the text accordingly.
The Corsair K100 has excellent build quality. Its plastic base and metal top plate exhibit a slight amount of flex, but it's hardly noticeable when using it as intended. The doubleshot PBT keycaps feel solid and hardly wobble. While all the black keycaps are made of PBT, the dedicated macro keys G1-G6 and the extra FPS and MOBA keycaps included are made of ABS. The incline feet are thick and grippy, and they shouldn't collapse when moving the keyboard around. It comes with a cushiony wrist rest that attaches magnetically.
The Corsair K100 has good ergonomic features. It's a straight board with two incline settings and a comfortable padded wrist rest that attaches magnetically.

The switches shouldn't cause much fatigue, and the included plushy wrist rest also helps with reducing any fatigue.
The Cherry MX Speed switches on our unit are quiet. It shouldn't bother anyone around you in a silent office. While we haven't tested it, we expect the variant with the Corsair OPX switches to be just as quiet.
Update 11/12/2021: The maximum polling rate of this keyboard is 8000Hz, as you can see in the settings. We originally tested the latency with the 4000Hz polling rate, so we had to update it to the latest firmware. The results below are from the 4000Hz polling rate because with our calculations, the latency will drop by less than 0.1 ms with the 8000Hz polling rate, which is a negligible difference.
The Corsair K100 has extremely low click latency, which is great for even the most competitive gamers. We tested it with the polling rate at 4000Hz.
