Great work with this. The design improvements are exactly what a LOT of people will be looking for. This mouse still works great as claw for small hands. For small and medium and large hands it's a great fingertip option. To me, this mouse combines the best philosophies of the EC, FK, and S series and puts them in one package.
Making the thumb groove less pronounced is a great decision. Lowering button height and width and overall size is fantastic. Making the click a little longer is much better as the np01 was too light and prone to accidental clicks. This plus the new coating and taller skates fixes everything.
Oh and 71 grams? Perfect weight. You should really aim for 71 grams for all your future releases, this weight is the perfect balance between light, stable, and sturdy build quality. Really good decisions all around and I hope this thing sells well for you guys, on paper it's an absolutely brilliant shape that reflects improvements and feedback you've received. Can't wait to see where you guys go with future mice and other peripheral releases.
I will say - I know you guys have an idea about the cord you are going for, but it is a bit stiff still.
