Not worth it.
The suction either didn't do anything, or left bruises. I tried every setting and followed the directions as best as possible (directions were basically non-existent). I had some black heads and couldn't get this machine to pull them up. Even on the lowest setting, if I left it sit on my skin for more than 2 seconds, I was left with a bruise, and still no black head removal.
