Great Compact system
I was a bit hesitant to purchase this but with my wife having those little plug-in fragrance devices in just about every outlet of the house I justified the purchase based on the price of replacing those little bottles every month. It took a bit to program the device and the QR code that takes you to a YouTube video is not the most helpful. I did find a different video and was able to quickly set up the date, time, and 5 events the device allows. I did take out the bottle when programing simply because the scent can be very strong when you have your face right up to the device for the 10 minutes it takes for set up. Once up and running, my wife commented several times that first day how much she like the scent (E11EVEN) and how well the scent reaches the majority of our home. I plan I purchasing a few of the Hour Glass units for her office and the master suite. She's excited to try the other scents!
