It deserves its 5 stars!

Added March 27, 2015:
I confirm all that I wrote following this addition; since then, almost five years, this mouse G700 runs daily wonderfully and never faint. The charging of the battery Duralock has not changed: maximum eight days.
HOWEVER, I nutilise more the Logitech SetPoint software that came with the mouse, but the Logitech Gaming Software; it is even more precise and efficient and regularly updates.
So I can really confirm the excellent quality and unquestionable reliability of this mouse.

Basic Comment, written in 2010:
I'm on my fifth laser mouse from Logitech, G700 and this is by far the best and most successful.

- Practical and economical: Finally a mouse that is recharged ultra quickly, without having to remove the battery, or put it on a pedestal. Just plug the USB cable during the night (even off PC), and voila. It can also be recharged during use, however, because of the tension of the cable, it automatically loses its mobility; despite this, it still remains very handy. You can vary the level of consumption via the software installed, and heavy use, it takes up to eight days (with a rechargeable battery Duracell Duralock) and four with the supplied battery.
- There is an on / off button, easy to handle.
- Very significant: there are removable and interchangeable pads. On my previous, skates slipped and badly rotted.
- Ultra precise: the millimeter on the screen, both in copy / paste in graphics software, it glides flawlessly on any surface and all colors.
- An aesthetic and perfect comfort: she marries very well the palm of the hand (for right-handed only), and I do not fatigue. The thumb rests on a pleasant, slightly rough surface that prevents sweating and skidding. The buttons are easily accessible and all are useful.
- The wheel is adjustable: with a button that allows the switch to freewheel (fast scrolling) or toothed wheel (precise scrolling).
- A specific Logitech SetPoint software and improved: with three programmable configurations easily, it automatically slides to a word processor in his office and then leave in a game; with presets for each of the three types of applications, everything is automatic and instantaneous, and controllable through three small orange lights. The many internal settings of SetPoint are in my opinion not superfluous. Regular updates are possible via the automatic update Logitech.

This, in conclusion, it was worth the money, and I can highly recommend this little gem, and in all types of use: games, office, drawing, internet ..., to have them all tested diligently with!
