Title: TERRIBLE!
Review: These items worked for about 4 times each. The plastic insert on the top that the metal lever rocks on to seal or unseal the stopper broke on both stoppers. The metal on the lever actually cuts into the plactic insert when you push it down to seal the bottle - cutting the plastic insert in half. When the plactic insert breaks, you can not seal the bottle. Don't waste you money. This product needs to be re-engineered.
