Unlike other oil burners, where you have to change out the wick or rock, all you need is a simple light bulb. You control the amount of light put off with the dimmer switch and the amount of aroma you want. YOUR IN CONTROL!!!

(To change fragrances all you simply do is wipe out the plate and pour your new fragrance in. REMEMBER do not mix old and new oil, because it will diminish the smell of the new fragrance)
