I have the z2 and personally love it.
considering pre-ordering the z3 (wireless version).
but they had a little issues on quality control on the z2. also I never tested all of its features but whatever I tried seemed to work just fine.
but a $200 mouse is crazy. wanted to hear from other users/people who have considered the purchase.
personally my use case is pure productivity. I don't use it for video games just browsing. the only macros I use is copy and paste. but I really like their trigger layout and holding other mice at this point just feels uncomfortable
