I had a problem with my Mobile Keys 25; squeaky key issue. So, I reported it and L6 replaced it promptly. (Thank you L6 support!) However, the replacement has the exact same issue, as seen below in this loop: EDIT: That Vine link was not accessible to anyone else, sorry. I removed it, it's not necessary anyway. So, I am contemplating just not bothering with another replacement and opening it up and lubing the mechanism myself. (Accepting the fact that it would probably void my warranty.) Has anyone done this?
