Review on Pack of 3 Automatic Measured Bottle Pourers - 1 oz (30 mL) Quick Shot Spirit Measure Pourer for Drinks, Wine, Cocktails - Home Bar Tools - PORE0016 (3) by Stephen Johnson

I have bought other measuring cups at liquor stores and they are much better than this one. The ball bearings inside don't stick, so you don't have to worry about them staying in the bottle for a while. The piece of plastic that fits into the neck of the bottle also doesn't snag like other brands that rip things in their fall but this one doesn't. I've used them many times since I bought them which helps at parties and keeps my friends from over pouring knowing exactly how strong their drink is. On top of that, they've added a nice wired pipe cleaner to help clean up after use. Fiction. I would definitely recommend and buy again!
