Firstly I am terribly sorry if this may have been answered before, I did try and do a quick search with no success.
On the page http://www.beerbongbros.co.uk/beer-bongs (http://www.beerbongbros.co.uk/beer-bongs), The second product along "Bottle Bong" has a user review on the page, but if you notice on the link I provided it does not show, it simply says "Average customer rating:". Thanks
