I have one very similar to this, and it puts out scent better than Scentsy warmers, but I feel like I'm burning through my essential & fragrance oils incredibly fast, and some of them are pricy. Are you supposed to mix the oil with something? I thought of water, but then I figured, since oil and water don't mix, it would just burn off the oil and leave the water behind. I tried adding vegetable oil, but that really diluted the scent.
Am I doing it wrong?
