Review on AmeriPour: Measured Pourer for Liquor Bottles by Angela Lott

Easy to use and fairly accurate. When I used my first dispenser, I didn't prime the dispenser properly, I got overflows (1.25oz or so, not 1.0oz). I went back and refilled the dispenser making sure all the bubbles were out and the fills were exactly 1.0 ounce. Choice of fill size and choice of color make them versatile for any bottle collection. The quality is excellent, they should last for years with minimal maintenance. All my whiskey bottles (except Glenfiddich) have 1.0 ounce gold filler so I only have two or even three days to decide if it was a spill. Recommend these dispensers even for a bottle. Very convenient.
