I am very happy to have bought this product, the disfuser does not make noise, it does not weigh much and I can take it anywhere, Can be used at home and in my office, it spreads the aroma of the oil in a very soft way and without exceeding it with a lovely Christmas Cheer. I highly recommend it, it is a plus that has different colors of lights, it seems magic to see it work during the night.
