It does look like a fantastic creation, to be totally honest though, it takes all the fun out of pouring a pint. I don't know if any other users work in a bar, but I do, I like it too, it's great to have a chat to customers and flick beer all over your work colleagues lol.
I was amazed when we got a Guinness Surger before, when it comes to products like this, the General Public int eh UK go MAD. When we got our Surger, our customers went absolutely ape **** that we wasn't "pouring it", no matter how much we told them it was cleaner, easier, quicker, they just didn't care. I'd be sceptical about getting them int eh UK. Festivals would be amazing with them/
