I just had to come back and tell you, this VSA is incredibly easy to install and works flawlessly seriously good value for money... for me if it saves one sale it's made me profit, it's feature-rich, simple to use and configure. But I have to say personally I do find them a little annoying as I do a lot of browsing, but I'm sure for every one person that does 10 will not. If set to correctly it can be used as a FAQ which will only benefit the customer an increase sales.
