Stromfresser par excellence !!!! Not for gamers !!

The mouse itself is really good in the hand and works well !!! That was it but also already for me!

Criticisms:
The thumb buttons are rather difficult to achieve for normal hands, since they are well placed because of the high mouse rather at the upper edge, especially in hectic Games, where I like to use all the buttons on your mouse, this is disturbing, and between the well for the thumb and the thumb keys is a disturbing edge !!

Although the wheel to work, but as an extra mouse button with my useless, at least, only if the wheel at certain locations, one notices here a kind of tactile feedback, so in games it reacts often not so for me this mouse not here use is !! As a mouse wheel to scroll it already is!

The clicking sounds of main keys so left and right are already after 1-2 months in use very annoying loud at a mouse in this price range I would have hoped for a little more .........!

Power consumption: Battery With hardly an option for few days at the end of battery and need few hours to be infected, by the design of my PC-table and without an extension of the cable but here not to use!
With a battery, it is a disaster for me !!!! After about 2-3 weeks the battery is empty! Ok I rarely turn if I do not use them! But my predecessor model kept the several months for the same use (and at that time I was playing even more)! And I'm talking about expensive brand batteries!

CONCLUSION: For me, this mouse was a bad buy, unfortunately, and have me use annoyed looked after about a year for an alternative mouse with the competition!
