Well, I find this issue in many private reviews,
even on the other Models too ("Sabre" etc.)
The weak (or faulty sensitive) switch of the whole line-up
is a known problem for people who fix their mouses instead of letting your warranty line run hot...
Please just improve the mentioned switch for the wheel instead of telling people of not knowing that problem.
(I have read this phrase more than a bunch of times in this forum and the problem MANY times in Amazon reviews too)
I´ll just solder out this tact-switch and change it for a better model.
An it-technican compared it to some competitors tact-switches and it´s just bad...
I still love the mouse and appreciate the product itself and it´s sturdiness, but the mentioned component is just garbage it seems.
