Review on Big D 767 Fully-Programmable Aerosol Dispenser: Beige, Covering 6000 cu ft - An Automatic Air Freshener for Restrooms, Offices, Schools, Restaurants, Hotels, Stores by Daniel Hhneverdie

We have been using standard 24/7 dispensers for years and I realized that 80% of aerosol product is wasted. We are only open to the public 35 hours a week. Based on a scheduled spray every 15 minutes, approximately 140 sprays per week are produced during business hours. BUT with the previous non-programmable dispenser we sprayed an additional 532 times when the building was empty meaning 4 out of 5 sprays were wasted! This "Big D 767" is great - the programming is actually more flexible than described in the product description. I set ours to only spray at 15 minute intervals Tuesday through Saturday from 9:45am to 5pm. A note: one of our two units had a problem - the wires to the motor were reversed, making it impossible to press the nozzle; but it only took about 5 minutes to fix it.
