I have to give this funnel 4 stars because they bring so much joy to us during festival season. They are a talking point at festivals, which always make us popular with our neighbours at camping festivals (our anecdotes are awful, so we need gadgets to make friends). I cannie give it 5 stars though, because they're not built like they used to be. I still have my first funnel from 2009 that came to Creamfields 2009 and went through university with me. It was dubbed Sir Foonelle and has been retired. It lasted for so long. I buy a new funnel every festival season because the valve breaks and the tube leaks after a couple of days of use. Last week I left this one in a field in Daresbury after the Creamfields 2013 festival, as all he same parts broke again. A must have tool but they aren't made to last anymore!
