I have all three 5oz,8oz and the larger 12oz? soap dispenser. All are so much better than anything else I've used that I ordered 3 more and sent them to my sister. She is blown away by the machined glass leak proof top, absolutely leak proof. Plus their ability to preserve your oils by the tight fit and small slot cut into the glass spout for the oil to flow. It's hard to describe exactly how they work but they are way cool and superior. My sister thinks I'm a genius.PS I water down the dish soap just a little so it comes out quickly.
