New to the forum, but have a problem that hopefully someone can help with. I have the sx m class and I love this thing. I just upgraded from the original sx, or "s class", and the battery cap on my m class feels like it is stripping out. The threads have always felt weird as everyone else has complained about. I never crank the cap down just snug it a little and recently the cap seems to be popping loose. I have emailed the company with no reply as of yet. Has anyone figured out a fix for this? I never has this issue with my other sx.
