Query: Invaluable addition to my kitchen accessories

I was surprised at how versatile this product is -- the built in, self-attaching filter is a great plus. The small size funnel just about fits flush with my 2oz tincture bottles, so be wary, these aren't for precision delivery to extra-small bottles. Other than that, I give this product an A.
