Review on 5.8 Inch Wide Mouth Canning Funnel Set: Stainless Steel Kitchen Funnels for Wide & Regular Mason Jars with Strainer - Large Food Canning Funnel by Erin Jackson

I carefully measured my Nalgen bottle that I use for Soylent and was sure this funnel would go down my throat, but I was wrong. This thing is exactly the same diameter, so it sits right over the neck of the Nalgene bottle. You can technically try to hold it in place and squeeze your product into the bottle, but it always squeezes a little and you end up spilling. So useless for my purposes. It's a decent funnel but the measurements listed were wrong and it was a waste of my money hence 2 stars.
