I was really quite surprised at how well this stopper works. I needed new kitchen sink plugs-as the metal ones had crapped out. I was saying to the husband that I don't know what size of those stainless steel & black rubber plugs to buy. I asked him to figure it out instead. lol
He returned with 2 of these sink stoppers. I was extremely skeptical that they would work. That they would leak or move out of place and let out all your water.
But do they ever work! They don't leak. They don't move while washing dishes. No trying to figure out plug sizes. Amazing gadget for $2. Love it.
