Not bad but could be improved 2

As a user in a professional setting of this mouse, I think is a demanding user of it.
All in all it works very well and in 6 months, she still did not let go of me, yet one can not say I'm especially careful with it (crushed in a bag, fell several times, unify tortured with displacement sensor pc, etc ...).

However I found him a few negatives, the first and quite boring:
- Roulette, when clicked to activate the 3rd Click, can roll and scroll the page (such as opening a web link in a new tab) or pull the left trigger of 2 horizontal clicks a backspace in navigation. This is quite unpleasant in the long run, and frankly I would have preferred that this mouse does not have this function and the horizontal wheel is harder when clicking to prevent accidental scrolling.
- Using it on multiple surface, a lacquer trousers and office, I have some problems with this black office loses mouse. I ended up putting a pocket beneath and the problem was resolved, but I have no problems with another Logitech mouse in wire, though older (I do not have the reference, 185 memory I think)
- The quality of plastic seems a little cheap, but it is only an appearance, because it is fairly resistant to my treatment.
Texture hand, kind of soft touch leatherette I think, was white on my mouse, and became very messy in a short time (pulls brown beige gray). Certainly related to the use by hands not always impeccable. It nempêche as to recover the original color, we must cling.
- FYI, I met a faith communication problems with the sensor, but this does not recur. I think a conflict on terrestrial band communication with other devices that caused the mouse clinched often enough solution: the user within 50 cm of the sensor.

On the plus side:
- Immediately detected by any computer (Windows, Ubuntu, Mac)
- Sleazy, even with battery
- Precise (on cardboard / matte material)
- Good battery life (until now)
- Compact, especially the sensor,
- Battery indicator
- Storage of the sensor in the mouse
- On / off button (essential when the computer in windows 8 is idle => if not wake the PC as soon as you move the mouse (depending on the machine))
