  1. I bought this K83 keyboard and almost immediately returned it to the seller. It would perfectly find my needs (RF mode + 2x BT devices) but it is just unusable. Finish quality - perfect. No doubts about it. Ergonomics - questionable. Why does it have glossy touchpad where finger touches are instantly visible and finder sticks to the surface rather than just slide easily ? Why is the touchpad rounded, not rectangle ? Why back button is located on the bottom where it can be pressed accidentaly very easily ? Why volume roll can be so easily and accidentally turned ? I could withstand all of that drawbacks for its features if not just terrible wireless range. If lying on my legs, it can hardly talk to the connected devices from 3 metres (9 ft). It is too much for this device then. Cursor does not work or jumps all over the screen. If I keep it in the air or if I keep it vertically so that its plastic bottom is directed towards the controled devices, then it gets better and 3 metres works 'just' but then its nothing close to ergonomic use. Even then touchpad is nowhere close to being 'precise'. Using it is just like a torment. I think the aluminium front limits E-M waves propagation and they put too small antenna inside and in the wrong place (somewhere in the middle). I couldn't verify this theory because this KB cannot be easily disassembled (no screws, just glue). It's not the problem of the location/interference/E-M noise etc. because in the same room Logitech K400 (RF) and K830 (RF/BT) worked perfectly at 3 metres. iPad can talk to my BT headphones over 10+ metres (30+ feet) crossing two walls... Logitech still does not have counterpart to K83. (Multi-device K375s has no touchpad, K830 is not easily switchable between multiple RF+BT devices).
