I had this diffuser for about a year and a half and it started getting very hot after it was bumped once (my puppies tail). It even stopped producing mist and would just bubble. The employees at saje were no help and I just left frustrated. I gave it two stars because I am very sad it's broken and I did like having it but the fact that there are just no options if something goes wrong (other than replacing it according to the store) really broke my heart. I guess my only advice is to save your money and buy a cheaper one so it's more easily replaced. High price doesn't mean high quality.
