I had one on holiday recently in Egypt. Having spent a day in the heat at the Pyramids and then a day in bed recovering, thought it may help before tackling a day in Luxor (already booked). It certainly did, I think they advertised it as a Bedoin Treatment but it is obviously the same thing. Go for it!
Had one of these on my hen weekend at Bath Spa. Yes, it was amazing. A man did mine, I was sort of dreading it but it was sooooo relaxing, I would love another any day.
