I've been using my Rebel DNA75C 21700 for two months expecting the buttons would eventually loosen up. They have not. All 4 buttons are as difficult to press today as they were when it arrived.
I don't see any places where buttons are rubbing on the case openings, there's a bit of gap all around all four. But they all require more than twice as much force as the buttons on my Mirage.
I'm wondering if the switches on the DNA board Rebel installed might be different/stiffer than the ones used on the Mirage.
Vendor Esauce didn't respond after asking for pictures.
I'd appreciate any advice on fixing this issue.
