This is cool. It's a very unique tennis ball bass drum beater. Great for very low volume situations. It makes the bass drum sound muted. Not too loud. Great for jazz.
I use this on a Pintech bass tower with a real head since the mesh wore out.
Reserving one star as it’s quite bouncy and unsure of durability. Might try another mesh and see if that tames it down. Price was affordable. Seems well made. If I can update this review in a few months I’ll change.
