On the design side, the mouse is really beautiful, very sober, so that the small details are noticed very well, a good point! Ergonomics, the mouse has a very good grip, the buttons are easy to reach, except perhaps for both the bottom (towards the wrist, the two buttons forming a "V"), which are a bit far, and the last button at the bottom (to the fingers this time, one above the button "Sniper"), I hesitate to put 4 stars for that .. but let's be generous, well worth the mouse :) Software and sensitivity side, mouse and software allow to have 3 levels of sensitivities, 3 are adjustable, for my part I have a level of "precision", a normal level, a bit fast perhaps to be considered as moderate, but very nearly, and a level "fast", the possibilities are still sufficient at this level, and mouse may well reach a really high sensitivity. There are various configurable profiles, six in total, which is more than enough for me! Of course macros buttons are adjustable, I do not insist on it. I think I made the turn .. If this is a final detail, it works very well, even on awkward media (avoid liquid still, I doubt it is very convenient for fishing).
In conclusion, this is a very good mouse, very versatile, it scores points everywhere and provides an arrangement of the buttons "macros" different from the block of buttons that are usually known, that I really appreciate. I do not regret my purchase!
