The software bucks sometimes and their biggest catch is that there is a roaming profile in both the mouse and on the jeweilgen PC. She has forgotten me in the beginning that there is a saved profile on the computer. Since I had to manually back on the stored on the PC profile switch. Stored in mouse profiles, it was impossible also to lay double-clicking on a thumb button, for example. This works but when it comes to an image stored on the PC profile. Why the software doing here differences in the programming ability is rather unclear.
But is beautiful again, as with other "G" products from Logitech, the profile changeover to gaming (program) basis, ie when pre-determined programs be started. So you can for each program have a different profile - even in eg Photoshop, where I need general keys other than the Firefox or in Windows. This is fun and you get used to it, that everything can go a little faster than before :)
The price is a little high ... maybe in the near future, so does anything else here. From the use and benefit from her you can recommend the mouse for both gamers and everyday office / Design / Office supplies fully - when schedules with a little time for the programming software. Because then the mouse develops the full potential.
