I used one with both my children. First time round I put it on much too late when the pain was already very strong and it didn't do anything. But second time round I put it on as soon as I started feeling the slightest pain, and that time round it worked really well, used it for a long time and when I felt it wasn't enough any more I went on to gas and air and water. I would say it makes sense to hire one, it's not that expensive and the worst thing that can happen is that it doesn't work for you and you have wasted a little bit of money...
