Review on Professional Grade Zoning Round Zone Damper by Ramon Hood

I have a 3 zone system running off an old DuroZone control board. I knew the original shocks were dying of motors because 2 out of 3 would whine loudly when opening or closing. These Ecojay shocks were easy to swap out and the wiring was simple (1,4,6 on the DuroZone board). So far, all 3 have been working quietly and reliably. A 5-year warranty is comforting peace of mind. The rubber seal around the vane is also a nice touch and should help my system run more efficiently as the old shocks didn't have that. 5 Stars!
