Review on Stainless Steel Classic Bottle Pour Tapered Spouts for Olive Oil, Liquor, Vinegar, Syrup or Oils - Includes Stainless Steel Funnels (Pack of 2) by Robert Espinoza

Tapered rubber rings will NOT hold ANYTHING securely. I have 4 bottles of high quality olive oil from different brands. This item does not reliably match any of them; everyone leaked. The only thing that should have been removed from this set was the funnel. I washed two sinks and tried on liquor bottles. While they appeared to be more reliable, at the end of a week of moderate use, they started shifting and dripping. Keep searching. It's garbage.
