Very nice construction and works flawlessly. Takes a couple of minutes when first setting it up, but once done you can pop the clutch on and off the hihat to your heart's content and have a quick setup/breakdown with identical clutch adjustment every time.
I tried similar products from other manufacturers, but this is the one I like best, the key differences of the Pearl being the lovely build quality, ease of use, and construction which will help to avoid any keyholeing.
