The last few days I've been finding that certain keys have been prone to outputting double characters. It seems to be the space key (MOOO) and certain other keys that involve that key, like c (MROO).
This Twiddler is 6-12 months old with about 3-hours of daily use and my previous one got stiffer instead of more sensitive. I'm wondering if this is normal or if perhaps it comes from space being an 'anchor' key. I use a modified Backspice (from early 2015), which shouldn't really be part of the issue, but it gives an idea of what keys are going to be affected and how often the key is used.
On a slightly different note, if this gets worse what's the outlook for warranty in this situation?
