I have heard really good things about this stuff. I was going to get some for my nervous horse but couldn't get hold of any near me and decided to try something else rather than order online. I bought Naf Magic instead and either he has relaxed considerably of his own accord (which is possible as I had recently moved him) or it works! I have found a stockist fairly near now and will definately try it before others if I need to use a calmer again.
