Very good quality product ... but doubts about durability
Extremely accurate pointer and extremely smooth button operation. It is very quiet and glides very well on the carpet.
I can only recommend it in terms of comfort and ease of use, it's the Rolls! I have not found a better tool for use in CAD (Autocad) and DTP / graphics (Adobe CS).
It is also fast and accurate for simulation (Prepar3D).
On the other hand, my first one that I bought at the end of 2016 has just failed me after only 2 years of good and loyal service (a few days after the end of the warranty!!!). A single left click sends several clicks to the PC, which is very annoying and makes it unusable. I think it's a sensor problem, which I had previously encountered with other manufacturers but never expected to find on a mouse at this price.
Well, considering its very real qualities, I'm ordering my replacement mouse today, but with an extended warranty ;)
In addition, it went from 129.00 € at the end of 2016 to 144.00 2 years later (+ 11.6%).
So I'm taking 2 stars off, not for its outstanding and irreproachable usability, but for its medium-term reliability and prohibitive price increase.
