Hi,
On my Mantis #q40 I have the problem that my right inner thumb key I use for navigating down always starts wiggling and today it broke completely. That's the key I propably press 500 times a day to read if not more. Anyone else facing issues with these buttons?

thumb keys
I don't have the same display, but have a focus 40, and have noticed issues with thumb keys on that too, mainly they start sticking, so you go to press it, release, but the button remains partially pressed, causing the display to keep scrolling and really make you lose your spot.
Hope you can find a way to fix this. Sorry I can't offer more help as I have 0 experience with the display in question.
Mantis Thumb Keys
Yes they wear out for me too. It seems to be the weakest link. It is disappointing. The best advice I have when you have a working display: use your screen reader's ability to reverse panning keys to reduce stress on the key. I do not recall if VoiceOver can do this, but JAWS and I think NVDA can. What I have done to help with muscle memory is assign reverse panning to certain apps that I use for certain things. For example, I keep my BookShare reading in Microsoft Edge and set reverse panning there. So I know when I am in Edge, I use the left key to pan forward. It isn't ideal and won't fix them breaking but can get a bit more mileage. You can also try auto scrolling from your screen reader. I have never had much success or comfort with that feature as I read different lines at different speeds. But some people fair well with it.
Same problem here
I sent mine in to be repaired for this reason, and it came back with the same problem. It's extremely frustrating.
