I really love my Glade Light Show. Not only is it an effective air freshener, but it is also a fun and basic light show unit.
I love that the strenght of the fragrance is adjustable, and I am pleased with the scents available despite the limited selection. The air freshener its self is fantastic, and the scent is distributed through out the room I keep my Glade Light Show in. I set mine on a medium setting, and I have been impressed with how long it lasts. The fact that refill oils are available is a plus definately.
The light show part of the air freshener is pretty cool, but it is basic. You can set the speed that the colors change to better suit your mood which is nice. This isn't anything spectacular, but it is a sweet function of an air freshener in my opinion.
Overall, I think it was money well spent on my part, I have been happy with the performance of The GLade Light Show.
