I was given a Jo Malone diffuser. I know it’s a very generous and expensive gift, but it barely smells 🤷🏼♀️ I have tried turning the sticks upside down, and have also ended up putting it in my bathroom as it’s the smallest room, but it still barely smells. Can’t see that I’m doing anything wrong, but I’ve had cheaper diffusers that are much more effective! Any tips?
