This one of more rviews about this mouse. First, the good.
1. New sensors including glass, you can use your mouse on any surface. They are promoting it like crazy, but it (the reason they want the wound one or both of the heavy glass hardware mouse does not seem a recipe for sand without them, I do not see? Glass ) is a really big problem with that. This new sensor, you must be a better means to track all aspects.
2. Rubber is excellent, the thumb buttons are very simple. 
3. Mouse DPI can be changed using the software ship immediately.
4. Travel pouch accessories very good receiver, USB charging cable, and (can be used in any USB charger perhaps), USB - output adapter, extension cable for USB.
4. New receiver, so the risk of not being connected directly to a computer breakdown and accidentally hit it.
5. New receiver "party" will work with other wireless devices that support the recipient. New plan to buy another Logitech input devices, and the long term, stick to this interface, very useful.
And The Bad:
- MX Revolution "SmartShift with an" innovative fit and can be activated by setting something straight scroll wheel to rotate at high speed will automatically switch to fix the sliding mode . The software is controlled to switch the button on the touch screen mode, any program that is intended. Then, get used to this feature, I can not be used without a mouse. Unfortunately, it is Logitech, mouse, and it fell with a new feature, to find again. Feedback will be placed in the toggle button can not be reprogrammed to an inexpensive mechanical means. This is a significant step backward. Since he was deposed, they think that has confused consumers, _unanimously_ public comments say otherwise. Because I suspect strongly it has been interrupted, more expensive than current methods to be implemented. 
- MX Revolution mouse is really leaving the cradle at night, it is easy to charge a cot. Performance MX is a small, fragile, have completely changed the power cord has a plug. This probably is better for laptop users, travelers and step back to the desktop user.

- Forward and Back buttons, the mouse is shifted forward. They are the Advanced Settings means that the thumb should meet some of the buttons. Revolution MX, both close to the hotel.
- MX Revolution, it was a dump has stopped using the stop. Night, leaving on the table, tomorrow will be the same level of toll-free. This works sometimes run to the MX. You, the performance of MX, battery level, the next day, "low" or "critical" despite the fact that, without turning the page, or if one was left around. On or not. This is irrelevant. (And, eventually, be added)
