I love this little gadget.
No more big rings and sticky materials.
This, for me (it's always subjective), works better than other solutions for the purpose. The only one that really seventified my snare drums, drastically, but at the same time elegantly, both aesthetically and soundwise. It's beautiful and well finished and easily permutable between drums (it just clips on the rim - use the instructions! - it's very easy but the little leather peg must be pulled).
May seem a bit expensive for what it seems to be before trying it, but, for me..., best money I ever spent on this type of small accessories. I just hope that it lasts - I want to believe so - it seems well engineered. Only time will tell about that. But I'm very happy so far.
