It's a french e-sport brand but has a lot of issues. Almost every user like it cause of ceramic feet that glide more than any other mice (too much i think) but most of them are experiencing left or right click issues or scrollwheel issue and have to send them back once or twice for another one.
As I was finding their whole esport concept and website odd, and as I found exactly the same shape and ceramic feet on other mice I tried to get a trace of their patent number.
I never had any trace of it nor any evidence that it has been developped by them in France. No trace or mention of any developpment dept on their website.
To be honest, I always thougth that they bought a license to put their brand on a chinese developed mouse (not only because it's built in China but because some other brands are selling exactly the same mouse, with sometimes different captors).
Moreover they are always saying they are working on the mouse to correct flaws and improve it but nothing ever happened. That's what led me to this conclusion. It's only my opinion, but I never understood all the buzz in esport around this brand.
