Review on 1Oz/30Ml Automatic Quick Shot Spirit Measure Pourer Drinks Wine Cocktail Dispenser Home Bar Tools - Yellow (6 Pack) by Tony Meyer

i like having a consistent amount poured and i believe these have been providing that.tight fight inside the bottles. i was expecting the collars to screw on the outside threads. they do not, but i guess that allows them to work on more bottles. there was a very minuscule amount of occasional leakage on my 750 ml makers mark bourbon bottle, but def not a game changer.i like the rubber caps that protect the openings.i have been able to remove a pourer from an empty bottle and reuse on a new bottle without a problem.
