After spilling a whole glass of milk into my first one of these, I instantly bought another. The feel of typing on this keyboard is great, as the keys are nice and smooth, well placed, well sized, and the keyboard has a fair amount of weight to prevent it from moving. I now use it on a large mousepad however the integrated rubber feet stop it from moving on really any surface. The rubberised top edge and surround give the keyboard a really nice feel and build quality on both units I have had is very impressive. The phone/tablet slot is good and an easier grab than off the desk, fits my iPhone 8 with thin case and an iPad without case, however thicker cases (>1.5mm for my phone) would not fit in without removing the case. Operating system wise this keyboard is truly agnostic, and does it very well. Used it with my Mac for a long time with everything working as expected, including all function keys (note does not have brightness like most bluetooth keyboards as these are replaced by device switching). This is a great keyboard for Mac users as the keys are very similarly aligned to the internal Macbook keyboards. On iOS tested on iPhone and iPad, all the function keys also work great, including home, search, volume, etc. Now a heavy windows user, everything is still just as amazing and function keys work well and a expected yet again. Each device pairing can also be either Bluetooth or a Unifying receiver, the latter of which I use on my Windows machine in parallel with my M720 mouse. All in all a very premium product for a great bargain, if I somehow damage mine again I will be buying a new one for sure, hasn't failed on me once. Congrats on getting to the end!
