It does not work well.
I have oily skin, and I used the power of oily skin, which is the strongest in the device, I tried it twice, the first time without exposing my skin to steam, and I do not see any black heads in the device, the second time I exposed my skin to steam for 11 minutes and I saw a little dirt in  the device , it is Doesn't work well.
