What special essential oil does it require? Are the enclosed bottles refillable?

I don’t think their bottles are refillable. Didn’t find this out until after I received item. And I can’t find refill bottles on Amazon.

Does this work with other oil brands, or is it exclusive to the brand it comes with?

You may find some generic capsules out there that you could put inside of the diffuser, but I would say the diffuser isn’t worth the money because it really doesn’t work. I’m not happy with it at all and I can’t return it because it’s past the 30 days.

When the fog comes out, the blue light will light up

Can I refill the brown bottles once they are used?

Hello, our brown bottle can be canned again, but it needs to use special essential oils.
