I have tried various touch paddles in the past and did not like them. One model (home brew), would stop working after awhile. I never found the cause of this issue. The second one I purchased and it had a metal plate to rest one's fist on....paddle worked fair but was tough to get used to as my fingers would tend to wander to the front of the sensing pad and would miss dits or dashes after awhile.
Art, W8CIT had an article in QST last year about a force touch paddle that sounded intriguing but I never built it up.
Being a mechanical type, I like paddles that have many adjustments available.
