Flair Smart Vent Bundle – Two 6×12-inch Vents with Two Puck Controllers. Automatically adjusts airflow to help balance room temperatures in a forced-air heating and cooling system. Includes two white Smart Vents, two original-generation Flair Pucks, Puck power adapters and cables, and original boxes. Purchased for our home but never put into regular use; ductwork adjustments during a renovation resolved our airflow imbalance. Excellent condition. Vent size refers to the duct opening, not the outside cover dimensions. $150 for the complete bundle. Cash, Venmo, or PayPal only. In-person pickup.
