I’ve been eyeing this product for awhile and finally took the plunge today. Firstly, I had no clue it makes a buzzing sound and vibrates. I assumed it was just to scrape. Secondly, the product gets kind of hot while using it. I tried it out for maybe 2 minutes and shut it off since it was getting too hot. Finally, it didn’t give me great results. I have a good bit of tiny blackheads that are so hard to remove. I’ve tried tools, strips, cleansers, etc but nothing worked or hurt. This got out a lot of oil, but didn’t take out many blackheads. It did scrape my skin and leave it looking like I scratched a couple day old sunburn though. I’ll try it again after a long hot shower but I’m not a fan of the vibration and the overheating part.
