I purchased the Air Wick Snuggle Plug-Ins Scented Oil 12 days ago. I plugged it in that day and set it on the lowest setting. I noticed in the last few days that the smell had greatly dissipated and when I looked at the fragrance bottle, it was all completely gone! In less than two weeks at the lowest setting! I'm generally purchase a different brand of air freshener, but when I saw the Snuggle scents that Air Wick had I figured I would give it a chance. Well, I will not be purchasing the product again because it is entirely to expensive, and way to much up keep, to have to refill it less than every two weeks. I will go back to using the other brand's products because they last longer and are cheaper.
