Very expensive, but it does work to refresh the house and is not heavy in the air. I have a dog...he gets wet and the Lampe Berger takes the wet dog smell out of the house right away. My problem is remembering to put the cap back on before all the oil has dissipated into the air. I bought two units, one for each end of the house.

It looks beautifull as you can choose the lamp. It let flow a freshness and a great perfume that you can also choose, there is hundreds of differents scents. But the thing is that you have to be willing to spend a lot of money. The oil is burning very quickly and the refills are pretty expensives.

Not the cheapest system around, but the quaintly is far superior. Looks classy and fits into any home decor. There is a huge variety or scents that you can fill the lamp with. Nice delivery system, not overpowering or cloying- just a nice soft accent.
