Please consider the following nitpicking. I wanted a detachable and "remote" numpad with replaceable switches and this one is exactly that, amazing!
However there's always something that can be improved:
- the 4 programable buttons at the top seem to use cheap-ish (?) LCD screens to display whatever icon you like, meaning the viewing angle on them is not ideal and changes colors partially drastically depending on what icons you've used
- these LCD screens have a peculiar preference for blue and white just like the preloaded icons come in, both in terms of displaying accurate colors and viewing angles; self-made icons using photoshop would show the limitations of those screen really quickly - drop shadows wouldn't get displayed properly, colors such as yellow I had visible more as orange, red would have to be in a specific tone otherwise the viewing angles would be bad, etc. the Icons seemingly have to be a bit more simple overall
- the keycaps above the LCD screens are semi thick transparent plastic caps, from my perspective and use case I see roughly 50% of the screen, the rest is button edges that I actively see
- they are hugely unsatisfying to use in direct comparison to the cherry MX switches used everywhere else, they barely produce an audible click and it almost feels like you press on a solid plastic button that is just decoration and doesn't actually do anything, if you like a solid clicking sound or expect a clear feeling of actuation then those won't be your favourite
Something else possibly interesting to know:
- I managed to connect the numpad to the keyboard using 3 extensions, 1x 90 degree angle (roughly 3cm), 1x 20cm extension usb c cable and 1x 50cm extension usb c cable - a total of roughly 73 cm and it works, for reference it did NOT work with a single 1m usb c extension cable, however be careful this might also be dependent on the cables used to your experience might vary; it'll definitely work with the 15cm cable that comes from mountain themselves
What does this mean for you? Again important to note, it's very use case specific - if you plan on using the numpad further away from the keyboard then you might see less of the icons, their colors have to be fine tuned and compromises have to be made as to what you want to display. I consider my use case to be rather unique and thus expect this to be a problem for a minority only. Despite all of this, I would buy this thing again in a heartbeat!
