So I've been daily-driving the Z2 for about a couple of months, seeing if it could replace my old Razer Naga Trinity, and while I do like it and I'm happy enough with it to use it long-term, there are issues and areas to improve.

Firstly, not enough thumb buttons, and they're not in the right spot. I'm used to having thumb buttons basically also in the same place as the thumb rest, particularly with the seven-button side panel for the Trinity. Raising my thumb up to use the thumb buttons isn't a huge deal, but it would be nicer if they were in a more comfortable position. Also, the mouse wheel click has more resistance than I'd like - it's loosened up over time, but it takes more force than I'm used to.

Also, just two buttons is a bit lackluster - I would really like four buttons in a traditional gamepad-style diamond pattern. I'm honestly surprised there's barely any mice that has that kind of setup - there was one that's now discontinued and impossible to get these days, and the 8BitDo N30, which has a d-pad but, uh, is styled after the NES controller to a fault. A diamond thumb button setup would be fairly intuitive for most people.

The ergonomics also need some severe improvement. Apparently my hands are fairly small and yet my hand gets kinda cramped sometimes using the Z2, there's just no natural resting spot for my pinky finger. This is something I've never experienced with the Trinity.

Also, I haven't been able to get profile auto-switching to work, even on games with profiles included in the software. Thankfully manual switching is fine, but I imagine it'd get annoying with lots of profiles.

But really, the main things I'd improve for the Z3 are more thumb buttons and a better form factor. Also, considering the gyro functionality, if I were you guys, I'd also go all-in on making the Z3 compatible as a controller for the Switch 2 - that system needs a dedicated mouse, and it would be neat to have a mouse that also has a thumbstick either for additional shortcuts or other kinds of analog functionality, potentially as an alternative to the gyro controls. It just makes perfect sense, IMO.
