I've been a fan of the older Sonor cymbal clamps for years, but after 20 years some need replacing. I recently bought a Tama stand that had one of these clamps and I love it, so I ordered four more from Thomann.
They can easily be clipped on or off with one hand in one second, and the thread grips the stand much better than my old ones. Once clipped on, you can still turn the clamp to adjust the tension. There's a nice design feature where one side is flat and the other has a small raised ring which fits inside the cymbal felt - so if you flip the clamp over it holds the felt in place more firmly. And the overall round shape let's the cymbal move more evenly than a wing nut.
Good design, well made, saves time, does the job. All good.
