I have spent a lot of money at saje over the years. Diffusers (multiple), oils, and loads of Christmas gifts. Unfortunately this item is below the standard I've come to expect from saje... Probably the worst item I've ever purchased from saje. The pads dry out extremely quickly (noticeably worse after the first use), with the fan on or off, on cool or warm temperatures. I've never said this but stay away from this item!
