On the one hand there was a strikingly puny radio reception. Frequent dropouts were the norm.
This costs 1 star.
What is there about the keyboard to say? Radio and mini keyboards I've tested a few. Again and again the request will be brought to the manufacturers of such products to develop a keyboard that is at least either Mac or Windows-compatible, or in the case of double and suitable for properly (!) Is suitable. It's here, in my opinion not the case.
The costs also a star.
Specifically: a weak point for me turned out to be the combination of F-keys and number keys. Those who work with two monitors, perhaps looking forward to the great potential of various desktop Spaces. For Macs also the functions "Dashboard", Mission Control, or Rocketdock happen and who want to be controlled? Where? Retrieving Settings, or from menus and views can be actually solved only on the F-keys, already hold alternatively with shortcuts and numeric keys, but then you have on the keyboard several keys pressed in addition and dislocated fingers. The same manufacturer also introduces a keyboard in the range that it ever has one line: the Rii Mini R8. It really works.
In the Mini ONE i28 buttons are larger. That certainly has advantages. The arrangement of the lower keys (CTRL / CTRL etc) here is better managed. In this respect, the keyboard is pleasant per se. It is not so cumbersome.
This is a star plus.
This Plus Star is but then again by playful that the keyboard itself is very rickety and there you can feel then not always, if you hold down a key already, or whether it is merely remembered for being so hangs loosely.
So a few.
Power 3 stars.
