Update: From 5 Mach 1!

Updated on 31.03.2014: So as a cheaper scrap. As soon as the mouse a month old, the left mouse button starts to squeak, not every time you print, but often. Quick Google search: Am I not the only one. No Joke. Something has not happened to me in years of PC interaction. That is also the producer for two weeks does not move and the battery lasts less than four more hours, I encouraged all the more in my decision to buy a Razer product more. Accustomed Easy returns through Amazon.

First the bad ratings I had here, some even date, held from purchase. After my beautiful Habu but after 5 years finally departed this life, had to be something new. Long story short: Because the Mamba of Habu is most similar in terms of size and also the thumb buttons fit well, there was this, model 2012, incidentally.

To take up the cudgels for the things once, the negative reviews I can not agree:
+ Mouse worked right away, without that I needed a driver.
+ She was already docked to the Dock.
+ In radio mode no (subjective) detectable delay. If I draufgehe, then is not that the _Maus_ lag (Gamer's will understand).
+ The dock and the mouse look naturally from noble.
+ Longest life now 8 hours piece, still 1 bar green.

The feature list is well known, so I need not there to take it. Since quite went my cloud software on the bag, I've installed the stand-alone version. Gibts something hidden on the manufacturer's website. Since then, peace, the system is re-used quickly.

One thing has bothered me but massively. Since then turn infected the Mamba, the PC wakes up reproducibly on after 10-20 minutes from the stand-by. The tool "powercfg" did not help that shows only the "USB root hub" as the final wake-up source.

In short, the Mamba is to blame. Namely installs the driver not only the mouse, but also a HID keyboard so that mouse buttons also send normal keyboard keys codes and macros can run. By default, even this mouse-keyboard can wake the PC from hibernation. This must be off:
1. Control Panel
2. Device Manager
3. At the bottom open "keyboards", not with USB Search *
4. There are now one or more "HID keyboard" en
- Open each node by double-clicking, it's a new dialogue
- There on the "Details"
- Select from the drop down "Hardware IDs"
- Check whether the first line reads the VID 1532, which is Razer. If yes, -> 5
5. In the tab "Power Management" Change in the same dialog
6. Check "device must the computer [...]" remove.
7. Close "OK", Device Manager

From then rest. Conclusion: So far, I would buy them again at any time.
