This was my first purchase of any product of this sort! I always used clippers and as anyone who has ever tried using clippers on their back knows what a pain that can be. I always ended up bleeding or missing small patches. Well this product really makes that a thing of the past. It is fast, easy and most of all you don't have to ask someone to help you. The blade is extremely sharp but protected with a guard so there is no possible way i can think of that you could get cut by it.I have used it for about a month now and I am completely satisfied with the purchase. The thing i like most is it is honestly like shaving with a razor and you can't even tell you have a back hair issue at all once your use it! It really cuts that close! I said previously this is my first purchase of such a product but honestly there is no need to look any farther for me because this is everything it claims to be and more. To anyone looking for a such a product you can go wrong with this! This thing is really a god send to me and that is why I took the time to write such a review. If it was junk I wouldn't hesitate to inform of that you but I hope my review helps anyone who is skeptical like I was to make the purchase.
