Got it today. It is just a stick of spring like some said but not everyone has such tight spring with such a length lying about in their house, so I bought it. It works just like I expected. As a kid I've run spring on my upper lip area without knowing anything about upper lip hair stuff and experienced some pain with the hairs being pulled off. So I knew what I was getting. The best way to avoid some pain would be to do it very slowly and feel each hair being pulled out as you slowly rotate it. You would experience some pain, just bear that as a warm up. After 2 or 3 slow rotations with the spring, increase the speed and do it fast because by this time your upper lip area would get used to the pain and you wouldn't feel much of pain. Bent it and place it on where there's hair and then straighten it and roll upwards till your nose. Will pull out lot of hair. It worked for me. Definitely there will be some hair remaining, just pull it out with your nail ( I can do that) or if you have tweezers use that and please don't clean this spring with water unless you want some rust in a few days. To clean it just bent it and use your fingers to tap and brush off the hair, you could also blow away the hair. The upper lip area will look red but I suppose it will fade away after 1 or 2 hours. If there's any change I'll update my review. The second picture with hair is the amount of hair I removed in just one rotation.
