This is a little weird at 1st, but I needed something for bladder leakage. I didnt want to use those weird eggs. I have been using these for a few months now and WHOA! I forgot about some of the muscles I have down there lol. But now, the bladder leakage has dropped dramatically! Nicely made, comfortable (As can be with something there) The string is strong and not going anywhere. I wish I wasnt so nervous to try this before!
