Bought this brand new from a local supplier for $190 when I installed a new hvac system earlier this year but didn't need it. I pulled it out and hooked it up briefly to compare to my existing smart thermostat and decided to keep with the one I had been using. When I pulled the wires out I had 2 wire release tabs break. It still holds the wire in great just would take a small screwdriver to get the wire out if you needed to. It is in new condition outside of the 2 clips pictured and worked great when it was hooked up for about 5 minutes.
