Great
worked well and looks good on the black drumhead
Did not last long
I play in a rock band and purchased this to reinforce the port I cut in my kick drum. Unfortunately the double sided tape did not hold for more than a handful of shows. I tried gluing this in place but overtime that didn't hold either. My recommendation would be to buy a ported head to begin with and if you are in need of a particular logo, buy the decal separately and apply that to the drum head. So far, that has been a much better option for me.
