Fresh, Light Scent and Easy to Move Around

I placed this diffuser in front of one of our AC units to help circulate the scent. My husband didn't even notice it at first, but after I showed it to him, he mentioned the fresh lemon smell. The scent is pleasant and fresh without being overpowering.

I also like that I can take the top off and move it into another room when I want to enjoy the fragrance somewhere else. The little funnel that came with it is a nice touch and makes handling the fragrance much easier.

One thing for other first-time diffuser users: I didn't realize at first that I needed to pull the plug out of the jar before I could use it! That was probably explained in a video somewhere, but it wasn't obvious to me.

Overall, I'm really enjoying it. It's a simple way to add a light, fresh scent without needing an outlet.

I put the triple diffuser in our entryway and it works really well there. You smell it as soon as you walk in, but it’s not too much. Looks really good.
