I have both good and bad to say about this product. The suction power is amazing if that is what you are looking for. Secondly, the suction power is a bad thing if you are not careful. It does leave you red deep hickies all over. I’ve found the trick is to adjust the suction power and head depending on the sensitivity of the part of the face you are working on. Also do it fast and in an outward motion. I bought it for my 13 year old and helping her use it was a learning experience. Good thing she is out of school for Christmas break for 2 more weeks. Poor thing. ?? I am confident we will eventually get the hang of it.
