Does as it should

Anonymous 02.04.2016

I always use these if my head is ported. Gives that little bit more protection against skin tears and damage from mics and cables. Would recommend this for anyone who ports their front head.
Some of them do take a bit more force to click the front and back rings together, but its not really an issue

Neat

Drumaddict 11.03.2025

Great way to create a nice neat appearance to a bass drum hole. Covers up any raggedy edges from when cutting the hole . Male hoop (outside of head) fits in nicely, female hoop (inside of head) is very tight and hard to get it to click into male hoop. Read instructions very carefully!

Looks good, but not easy to place it

Abhi 28.01.2020

Looks really good on the head, the adhesive is strong, but it wasn't so easy to put this in place. I hope they make this more efficient.
