I read a lot of reviews before I decided which diffuser to buy. I finally went with this one and am glad I did. I love it. It's easy to use, it lasts a long time, and the oils smell lovely. The features that I really looked for were that the light cold be turned off/on, that any type of oil could be used (citrus is one that comes to mind), that it was quiet, visually appealing, and had good reviews. I would highly recommend BellaSentials oil diffuser to others. The company also sent a free gift, which ended up being a really nice quality chapstick (something I use all of the time).
