Could've been betterArvosana 3/5
It is my first entry into wireless mouses. While it's good, could've been way better. I have two of those and everything that I describe applies to both.
Battery holds maybe a week of regular 8-12 working from home. And this is without LEDs and couple of other battery drain settings. For me, it can be more than that. Then you have to charge it up for couple of hours.
Sometimes it just disconnects and you have to re-plug the wireless dongle, which may be furious if you have it on the back of your PC. Other than that 2.4g connection is very strongh, I can go for 10-20 meters away and it will work (as it should since it's wifi).
Very lightweight, this might be a minus for someone, for me it is rather a plus.
Every button clicks firmly.
Definitely wait for sales our outlet, 100e is way too much for it.
