I tried alot of things for my PI and nothing really worked for me untill I tried Zenfel.I had PI between my fingers and forearm for over a week when I got ZenFel and it was a life saver for me.It made the blisters go down(probly from the scrubbing of the sand like substance in it) no more ozzing and the itching went way with in 5 min. and the rash was gone in about a day and a half.To bad it doesnt work for everyone.But if you are one of the lucky ones that it does work for I bet there is always a tube of it in the bathroom.Shoot I would pay 100 for it if I had to.Thats how good it worked for me.
