Review: Better than expected - Never bought anything like this before however I wanted to make a tincture using the percolation method. This dropper bottle is a much higher quality than I was expecting which was a pleasant surprise. The glass has a nice weight and thickness to it. The photo I’ve included shows it setup on a stand with the dried herbs and alcohol macerating overnight. A teeny tiny drop of fluid did seem to have slipped through the stopper even though it’s in the closed position. That’s not a big deal for my purposes though. The video shows it in action! 153 proof alcohol running through dried Soursop leaves. Why did you pick this product vs others?: the size is suitable for small batch making Leakage: one tiny drop of fluid after sitting overnight Build quality: sturdy
Review: Works great - Excellent purchase. Works as designed. Clean up is a breeze thanks to the tapered design of the stopcock.
