I was a little hesitant to order this plug, but am certainly glad that I did. It is the best plug I have ever used. It keeps your retention liquid almost air tight even with messy oils. I do an olive oil retention every month and since I purchased this plug I am able to retain for 24 hours. Works great with coffee retentions also. I would highly recommend purchasing this plug if you are into retentions and have problems with leaking.
