Useful but use with caution
Defiantly could see the blackheads coming out with the tool and was very useful. I was on the lowest setting but the suction is still powerful. Be careful when using. The instructions say no more than a few seconds and I still had an area that is now bruises and blood came to the surface. I had a bruise on my chin for a few days from the blood coming to the surface. Overall very helpful and you can see all the blackheads come out.
