I did fly with a PIEP for a number of years and it worked well.

I have a Piep plumbed together with a Sage CV, and I still use it.
Bought it new back in the late 1970's. It's my primary audio,
and with the Sage, works as a back-up for failure of the main glider
computer....... I also have a main battery with sometimes two back up
batteries, thanks to having a main (and only) battery fail on me at the
1985 WGC in Rieti. -- That was not a good day, and I learned an
important lesson there....
