Anyone tried the MUTU method?

I've seen loads of ads and just signed up for the free trial, but it feels a bit "too good to be true" and weird. They claim 100% in a trial saw prolapse improvement, but that sounds dodgy to me, probably a sample of one haha. But they also say they work with the NHS... but no physio I've seen has pointed me to it. I'm interested if anyone's had any joy with it? It does seem like exactly what I've been hoping the physios would give me to do (all I've been given is kegels by multiple physios which is so frustrating as i wanted a programme to follow).
