Aromatherapy Diffuser

I first saw these in a garden centre and really felt the difference in the air, how fresh it felt. I made up my mind to get one but couldn't at that time.
I eventually got one earlier this year and it is fantastic. It has plain water inside with a few drops of oil and the steam that comes out just makes everywhere smell so much fresher.
I'm not a smoker so don't know how they would fare against that but this works for me and it is so relaxing to have the blue light on and to watch the steam which is more like smoke but without the effects of smoke, coming out of the top.

I can smell this even downstairs and it's just wonderful after a stressful day.
