Protects the hoop very good, does the job. The other side didn't hold during the first transport (I use Hardcase), but then I pressed it in it's place and now it seems to hold but not super sturdy.
Adds a little bit of thickness to your hoop, so if your bass drum pedal's clamp doesn't have a little extra room when you are using it with just the hoop, this will not work, but I have no issues with that. I guess that with most hoops and pedals this will work.
