Do not buy this. The design is poor. My husband had to "fix" the battery compartment because the batteries did not make contact with metal and it wouldn't turn on. He got it working but it does a terrible job on anthing bigger than a small eye makeup brush. And the round bowl is impossible to empty/clean.
Great idea for a product, but poorly designed and manufactured.
