I use this product for ten years without a problem. It is not easy to use the first few times, but it gives you maximum freedom of movement. Also I do not look at the rules disgusted way as before with towels. The blood is fresh and red, no unpleasant odor, and I know exactly how much blood I lost that day. I keep it in place 24 hours without problems. The rules are natural, using a simple and natural method.
