The build quality of the keyboard is excellent - I went for the Gateron Red switches, which are satisfyingly clacky. The keys do feel a little squashed - some muscle memory will need to be relearnt to be accurate touch typing.

I bought this because I wanted a number pad keyboard - because it's a shrunk down size, you lose the spacing around the arrow keys, which can be a bit awkward at times. The number pad is fine, but the zero key is tiny - as someone who is normally a touch typist on the number pad, this does get a bit frustrating.

Battery life is OK - I have the white backlight on continuously and use Bluetooth. It has a very aggressive saving mode and will go into sleep after a minute or so of not being used. When it does drop, it goes very quickly and I haven't spotted where the low battery indicator is.

I love that you can have 3 devices paired to this - swapping is easy and you don't have to mess about with forgetting and re-pairing the keyboard.

Overall, it's a great looking keyboard - I would have liked a little more spacing out, but my muscle memory will remap I'm sure! I would definitely recommend this if you want a compact, sturdy wireless keyboard. The keyboard does also sit quite high, so I'd recommend getting the wrist rest as well.
