Has anyone here got any experience of these please. I've read their bumf on the internet but as its their advertising I'm a little bit cynical as they would be unlikely to point out their faults! I'm especially interested in any feedback to do with the unit based at Harrow on the Hill. Its only been open a year and the treatment regime is meant to last 18-24 months, so I know this is a long shot but any info (however small) gratefully received. Many thanks
