I am not happy with my M5 also, the display is not as bright and crisp as my LX5. I brought it to Marcum and they told me they adjusted the display but it was no different. That new display is junk, do not know why they messed with it.
Marcum had a deal on old stock on their website. I picked a 2017 lx3tci for under $300 shipped. I looked at the m series but I’ll stick to tried n tested lx series..
