1. Works on Win 7 requires no driver installation.
2. The mouse is powered by a AA cell and thus remains pleasantly light. Power consumption 15 mA. However, it is mechanically somewhat small, much smaller than my previous Logitech RX250.
3. The keyboard - also a lightweight - with two microcells, power consumption 10 mA. The pure operating time is therefore likely to be about 80 hours. On the desk my copy is perfect, so is not warped. To write texts quite well, however, are better. Bright key noise.
4. Both keyboard and mouse go natural in a standby mode to save power. If you have previously worked only with wired mice, it is strange that the mouse up to 6 sec is required to re-awakening, the Tastaur is there faster.
5. The absence of the key with the angle brackets is a bit annoying, the keys for the Windows Start menu, I would have liked, however can do without. In my e-mail program the shortcut keys ALT + 60 or ALT + 62 do not work!
6. At the most annoying however is the bright twang in the audio channels. This is regardless of the volume setting and is generated by the 2.4 GHz receiver. Subtracting the receiver off, is quiet again.
Addendum: the receiver was connected to a front USB socket, at a rear port (much closer to the audio connectors) can not hear buzzing. A wired keyboard or mouse on that front connection not produce hum.
