Endgame gear xm2w 4k v2

Question for people that use/d this mouse, how is your experience with it?

I have the xm1r and was thinking someday in the future to buy a wireless xm1/2. I searched a bit on the V2 and saw some people complaint about some QC problems and saying that the coating isn't as it used to be on older generations, so it made me a bit skeptical about buying one.
