That's a bit short!
This mouse is exactly the same as my old "Urban Factory Ergo Mouse". It must be its new name... the advantage is that it is cheaper than the latter...
It is a mouse marketed by https://ceratech.co.uk/ and it works very well under Linux (I don't know why Linux is always missing from the lists of compatible operating systems...).
The ergonomic side of this mouse is appreciable and has a real efficiency in terms of comfort. The mouse wheel is wide and very comfortable for drawing in 3D. The notches are not too pronounced (but they are not disengageable like on other brands).
As for reliability, my previous mouse had the cable sheath come off the mouse, but I was able to glue it back on. And then it died because the click wheel didn't work anymore (despite a dismantling and cleaning), after about 2-3 years. Not very robust, so...
What I think is a shame is that the cable is so short. It is about 43 cm shorter than my other mouse which is not ergonomic! With a tower computer at my feet, on the left side, and the mouse on the right, it's a bit of a stretch. That's why I'm only putting in 7. I'm willing to pay a few more euros to get a proper cable length.
And so despite the low reliability and short cable length, I think it's a good mouse.
