Incredible deal for a lot of three Flair smart vents and three puck thermostats. You’re getting a great deal. I bought these on Amazon in March but I cannot use them in my house. It is too late to return on Amazon. This is great for you!

One set is still in the box and has never been opened. The other two sets have been opened for literally one day after I bought them brand new in March. So you are getting three basically brand new sets.
