Long ago that this type of cap intrigued me, and I fell for this model that I find perfect. The valve can close the opening when the bottle is placed, sheltering the content of air and dust, the flow is steady and without bubbles, so no splashing, control flow is much more accurate that the neck, and it is much cleaner because you do not touch the stopper with your hand, no risk of getting your hands dirty (easy enough with a bottle of oil for example!), few drips to Use a little bit of paper towel time and time and hop. The construction seems solid, the finish is perfect, and the quality / price ratio okay. I'm happy with my purchase and I recommend this product!
