SuproBarware Automatic Measured Bottle Pourer - Quick Shot Spirit Measure Pourer Drinks Wine Cocktail Dispenser Home Bar Tools - 1oz/30ml (4 Pack)

I've tested two and, after some coaxing the ball bearings into actually moving, they are reliable. There's no messy leaks and I can see why this design is the standard in bars. The measure itself, 31ml-32ml, seems like it's not quite perfect but is easily close enough to 30ml for your home and bar work (I tested both water and vodka in a 100ml measuring cylinder by pouring at a 45deg angle, 3 measures, one after the other, and dividing by 3). Obviously I haven't used these a ton, but even if these wore out in 3 months - even 1 month - , they'd be saving a lot of time (and therefore money) in a bar setting. Not sure about more viscous liqueurs like Baileys or Amaretto so cannot report if they mismeasure them or if they might need a good rinse before switching to a new bottle. Otherwise I have to give 5 stars. One of Amazons actually good products! WAY better than the 50ml chrome ball pourer I got at the same time.

Brilliant, absolutely perfect 30ml pours! No leakage and so easy to use, wish I'd bought years ago

Helps to measure drinks very well. Fits all bottles tightly

Nice brightly coloured pourers, they all work as they should and have a cap you can put over the end once your finished they also come supplied with a sleeve you can fit over the bottle fitting if the bottle opening is to large for the Pourer good price for 4 units, we are very pleased with our purchase and would buy again if needed.

These are great, going to be perfect for my Son's wedding reception soon, even measure Fully recomend

The measureing system does not work reliably on thick creamy liqueurs such as a Baileys or Tequila Rose. Works ok on spirits.

Excellent product allows you to only Measure the amount you would buy. Certainly makes the bottle lasts longer

Seems to be OK without yet trying them out

Nikel sauf un ms parfait

Shipping was fast with next day delivery.These stoppers changed the game and allowed me to pour measured shots with ease.They do not however fit the larger mouth bottles of liquor,like the half gallons and gallons,but they worked well for the fifths and most pints.

Awesome products and superfast delivery 🚚 I highly recommend this seller.
