It's tiny, about the size of a quarter so you really need to soak the pad with a scented oil to get the fragrance to be noticed and last. That is why I have four stars instead of five. It appears well made and just slides right on a car vent. With the numerous felt pads, you can change scents often if you wish.
I love this diffuser. Goes in my car, on the vent, like all the other car clip air fresheners but it’ll never run out of scent. As long as you put essential oils on the sponge it you will release the scents. Totally awesome!!
Ordering was easy and it arrived promptly. The clip part is pretty and looks nice clipped to the air vent. The scents sent we're very nice. We did need to really soak the circle that hold the oil. Otherwise it did not diffuse properly. So far, it is my opinion that this was a nice addition to my daily commute. Thinking about getting one as a gift for a friend.
