Reliable but need to pre-measure
Purchased

Unless your flask is clear (God knows I'd love a cut glass flask -- see Grand Budapest Hotel), you run the same issue I have with other funnels -- spillage. Which is fine if you're using the cheap stuff, but you don't want to spare a drip otherwise. Fits nicely -- just difficult to see when you're full (before it's too late).
