I own two Lampe Berger burners & really like what they do for a room. They look nice & not at all out of place, & once you have settled on a oil fragrance It is a daily ritual that you very soon get in the habit of doing to refresh any room. I purchased these three smaller bottles of oil because previously i had stuck to my original choice (Paris Chic) & needed to broaden my horizons. The three i brought are very nice too. I didn't think the price was too bad either. But obviously the litre bottles are far more economical once you know your preferences.
