Review on Chefast Set of 8 Stainless Steel Bottle Pourers with 10 Long Dust Caps, 2 Cocktail Picks, Brush, and Storage Bag - Premium Metal Toppers for Liquor Spout Pourer, Oil & Vinegar Dispenser by Daron Ellis

Used at home. A good, snug fit and tip caps are essential for fruit fly protection. UPDATE: Turns out the tip caps are *TOO* tight. The tiniest bit of moisture or alcohol residue on the spout will basically cement the tip coating in place, and the only way to remove it without damaging the spout is to run it under very hot water until it loosens. A big problem. I messed up two of them by trying to pry off the tip with pliers. However. I still recommend them if you modify them just a bit: take a pair of sharp scissors and cut off about 40% of the bottom of the rubber tip caps. This means they cannot grab the widest part of the nose of the spout. They will still be snug enough to keep bugs out.
