I love lavender oils, and I use them for my diffusers in the bathroom.This is my first time trying this brand and while they smell absolutely amazing, the scent is very weak and doesn't really fill the room like my previous one.Feels like there is more oil than scent. I was slightly disappointed because these are not cheap by any means.Likely won't try again, but if you are using for massages or other uses this would likely suffice, just not as a diffuser, in my opinion.
