I bought this portable difuser, and for some reason the scent wasn't propagating at all, it didn't matter how many drops I added to the pad. I made peace with it, because I imagined that is how it works, since its such small unit. After voicing it to Lola, she told me something may be wrong with the unit, and she gave me 3 options to resolve. She always goes above and beyond and I'm so glad I found her company.
Works great. I am going to order a 2nd one. The scent doesn't let out till its on.
