This device is one of the best chain rattlers, as recommended to me by other drummers, and did not disappoint. Also comes with useful instruction on how long to make the chain depending on what cymbal you have, would highly recommend.
Really happy with this, I've transformed my vintage Zyn crash/ride into a lovely sizzle ride. Easy to use - just replaces the original felt jobbie on top of your cymbal and screws in using the existing wingnut. Trim to length so it doesn't droop over the edge and it's done. Excellent!
