I am giving this 5 stars because it actually works the way it was intended. Gives me a perfect air seal in my cylinder and my Lonex Aug nozzle.
On another note, the cushion pad that comes in the cylinder head is more like a rubberized plastic and cannot be glued too. I tried super gluing a 70D 3/16" sorbo bad to it, left it over night, and the pad just fell off. The good news is, the plastic cushion is easily removable. So what I plan to do in the immediate future is to buy a 1/4" sorbo pad and use that instead. Then it should be perfect. I just wanted to share this information so nobody makes the same mistake I did.
