This may be a bonehead question but I have been using a few USR40 and I'm finding them really difficult to use because of the connectors. Several have had the back plastic piece pop off of the remote 1 and 2 terminations. I prefer the using wire caps, so the USR1-40 is looking pretty good. Will I run into any problems with switching the remotes over to the USR1-40 with the USR2-40's as my main switch? TIA.
