As an advantage, I feel also the Logitech Unifying receiver into the mouse with me in addition to a Logitech K340 Compact Keyboard is connected. Actually, I had always resisted me against the use of additional USB adapters but at the present-day micro-design, the receiver can remain permanently without problems in the notebook and are typical of the Bluetooth mice and keyboards used previously by my sporadic connection problems belong to the past at.
more details are struck me positively:
- Fits comfortably in your hand
- Can also be operated with a single battery for lighter weight (thanks for the hint in another review, I would have never tried)
- Change between Mausradfreilauf and ratchet setting by pressing the mouse wheel
- High quality
The battery life in intensive use with a single battery is, in my experience at about one month. I find that absolutely acceptable, especially because I use rechargeable batteries.
