I've always been a fan of riveted cymbals, so it's nice to have the option to add a sizzle to any other cymbal too. I've had a couple of the Pro Mark sizzlers for a few years, but never understood why they were so clunky and how the top section was intended to work with the felt! These Meinl equivalents are much more tidy though, and work a treat.
My only negative thing with them is that they're a bit over priced for what they are - you could make a DIY equivalent with a plug chain and a keyring for a few pennies, but out of laziness I just treated myself to the real deal.
Overall, yes, because they're branded, they're a little overpriced, but they work a treat, so why not?!
