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 Craig Mcdonald

fillers are accurate and work well when new and actually work. They stopped working after a few months. I found myself removing the attachments, shaking them and rinsing them repeatedly to get them working. I've only used them on vodka and bourbon bottles. Now two out of three pours don't work anymore, they measure wrong and won't stop pouring. The plastic around the metal balls looks pixelated, they no longer work. I don't think I will buy them again or recommend them.
