I think I have a bad one. The funnel is transparent. It also leaks a little when the valve is open, but slowly. That's why we will do go back and try another one. I will update the review. If it isn't leaking it would be very helpful. Update 8/16/2014: Revain quickly replaced the leaking funnel. Looking at the bottom of the funnel sees it looks like there is a seam where the two halves of the plastic meet to form the bowl of the funnel and the seam wasn't even - there was a small step so the rubber washer couldn't get a tight fit so I took 1500 grit sandpaper and sanded down a small step...it leaked a lot less but still leaking.Then I lubricated the bottom of the funnel with a small amount of petroleum jelly rubbing the rubber washer with the Masc henfilter touched a, which in turn fits into a black thread attached to the blue plastic thing that is the valve. Now it flows very slowly and can actually be used for my purposes (I keep a rag handy). I'm leaving a 2 star rating because while I want to love this thing, it's too much trouble to stop licking it.
