Very useful! I had a lot of small, deep blackheads on my nose and forehead that I haven't been able to move for literal years after working in a shop with an open front to a busy road (the dust in the air from the road really messed up my skin and air con in an open front shop does nothing in Queensland summer). I've tried so many products on the market and nothing worked. This tool has finally removed them and my skin looks so clear! It's also helped my husband's skin a lot in removing blackheads and preventing big, painful pimples from forming (he's a tradesman so his pores get clogged a lot, the blackheads usually become pimples).
