You should have asked "how many T2+'s are bad". I mean
they just keep breaking or having crazy problems. Today's
was that the T2+ commands in the LCD section whether macro's
or single commands would not work. LED's on the RP-1
acted erratic.

Replaced the RP-1 with no luck, put it back in and programmed
up a new T2+ and system works flawless again. This same
guy has had almost every thing go wrong with the original
T2 then now 2 different T2+'s since switching to the current
model. At least the customer is nice and has cold beer
on tap.
