A fan of Logitech mice very disappointed

In terms of ergonomics, no complaints (except that I find futile side buttons).

But there are two huge flaws:

1) ridiculous autonomy. The mouse is equipped with a rechargeable battery. Autonomy is at least 2.3 times lower than the "old" revolution. Solution: Always have a charged battery at hand. In addition, the recharging cradle it was still much better than USB cable to connect to the mouse.

2) many worries "bad" cliques with this mouse.

Big positive is very strong, failing to return to the previous generation, I look forward to see what will give her replacement.
