Hi

My only connection with BRG is finding them on a web search. Other than that, I can't say anything about them.

> I would avoid BRG clocks.  I've used them in two different companies now and they're pretty much junk in my opinion.  Both of the clocks I used had IRIG inputs and they only sort of work.  They seem to randomly lose IRIG lock every few days and will easily get 1/2 second off, even when locked.  The user interface is incomprehensible and takes me 20 minutes to figure out every time I have to adjust the UTC offset to display local time.  Finally the instruction manuals are too complicated to be useful.  It seems like they just keep tacking on features to firmware written 20 years ago, even with the new features don't fit the UI model.  When IRIG time wouldn't sync up on one of the units, I took it apart and found the clock to be constructed of a metal picture frame with the circuit boards loosely laying inside some green crafting foam and wires running all over the place.  Even my electronics projects when I was a kid looked more professional than these clocks.  When I reassembled it, the IRIG feature mysteriously started working again, sort of.
