Flair Smart Vent 10x10 (White), AC Vent Cover for Walls and Ceilings.

Finally set these up and love the solution. Even a pro HVAC Duct worker with all their gadgets can’t provide a solution this good. Even if they perfectly balance your vents you don’t have the control to modify anything on the fly. These vents allow constant modifications to allow the perfect temp in each room. As for value, these are by far more cost effective vs hiring an HVAC company. I also love the way the diffuser works and looks. The sizing was perfect as well. The response time is obviously better if you have a great network all over your home, but will still work at a distance. Overall I am very happy I bought these for my home. I have 5 pucks so far, 13 vents and 2 controllers.
