For the mouse I find absolutely brilliant, apart from one thing: the famous roulette supposedly revolutionary. Okay, being able to scroll quickly décranter when it's great fun and it is very accurate (if the wheel stops in his tracks, the scanning stops net), but the problem is that 'notched in fashion one does not feel much notches.
Personally it does not bother me badly because I am used to mice with fairly marked notches so it's confusing at first. Also I made a standard exchange of the complete pack, as the first I got the problem was even more pronounced (I could even move the wheel and scroll simply by shaking the mouse!). Now with the replacement pack the wheel of the new mouse works best, but I'm not totally satisfied. Finally it seems that it's like that on all MX Rev ...
One point I want to point out: the Bluetooth connection has nothing to do with RF connection paperboard of MX1000! With the latter I had trouble moving the cursor not being able 2m receiver, whereas with two elements of this package I capture at least 7m away. Really nice to use the keyboard / mouse being in bed By cons sync via the BT dongle can be quite temperamental sometimes, but it still not finished walking.
I also wish to congratulate Amazon for their return SAV handy system: they send us immediately the same product upon confirmation of the return and was a 30d time to send them the product defective. This is really the top, I've never seen this at other online sellers, bravo!
In the end, although the mouse wheel is not tip top, I recommend this package anyway because it works wonders, mouse and keyboard are very design and excellent reach.
