Review on 🍹 SEO-Optimized 1oz/30ml Automatic Measured Bottle Pourer - Pack of 4 Quick Shot Spirit Measure Pourer for Drinks, Wine, Cocktails - Home Bar Essential by Stacey Williams

These spouts basically do the job. I've found that they pour unevenly - the pour can be anywhere from 0.75 oz to 1.25 oz. They seem cheap, but then again, for the most part, they work. One problem is that the plastic that fits into the neck of the bottle is very hard. I had to heat the plastic under hot tap water before fully fitting it into a standard 750ml bottle. If this is not done in advance, there will be no seals and leaks. Otherwise they are fine. Throw them in the water at night when you're done drinking and they'll last a while. Highly recommended if you like Malort.
