I purchased 5 bottles of snail elixir after seeing a advert in the newspaper the star it said it would repair your knee joints if they are worn out,and if your not happy,you can have a refund I brought I bottle ,but did not work ,but its not going to just one bottle so I brought 4 more bottles , and my knees are no better whatsoever, and the adverts says it starts working from day one,i spent £130-and when I sent the 5 bottles back for a refund as promised ,as it did not work they just fob you off, its fraud, them make big claims and say it works but it don't so anyone out there don't buy from this horrible cowboy firm
