after reading many of the reviews for this thing, its sounds like people dont know how to think outside the box when trying to get this thing on. all you have to is put the front ring in place, and then put the head face-down on a hard surface, put the second ring on as much as you can, and then take a hammer and a flat head screwdriver and gently tap the ring around the outside edge until it snaps in place. it took me a while to think of this after wrestling with it, but after you get it on, its pretty cool lookin. but it is a little over priced for a piece of plastic.

I bought this ring for my bass drum and man!! does it look cool or what? well, I knew there was some cutting involved, I asked the guys at Guitar center in Arlington, TX to do it for me and man they did a good job. Overall if you have never installed one yourself, have an expert do it for you, don't risk a good piece.

Okay, I was really hesitant to buy this after reading so many reviews where people recommend removing adhesive from one side because it won't fit otherwise. This is just WRONG. Granted, it is very difficult to get the two rings to snap together. What I ended up doing was going to the hardware store and buying two small 1" C-clamps. Does the trick. Once you get it on (adhesive on both sides!) it resonates with the head perfectly with the head. I would definitely recommend getting these but also being patient and realizing that it SHOULD be difficult to snap together if you want it to not rattle.

When I bought this i had also bought a brand new head with it, and i believe that was the mistake i made, cause i installed the Port first, then installed the head, and I believe the head stretched, causing the inside piece to come off. While trying to reinstall, the inside piece actually broke, now rendering useless. It does look pretty though...

This is not well made. I don't think the company even tried using these things. The ring has a front and a back: they both have adhesive facing the drum head. However, the two rings dont fit together properly so the adhesive will only work on the front side. You are better off just cutting a circle and coloring the edge of it with your favorite color marker than buying this piece of garbage.
