A great product for keeping your Pearl bass drum rim neat and always in the same orientation (and can be installed on f.e. Yamaha RC, Sonor Delite…). Price is decent, I think, for the years of service it provides. The reason for stars (not 5) is the attachment screw (hard to operate as it is small, but more importantly it protrudes out and can interfere with attaching your pedal) and the provided 3M non-slip surface tape is too much like grade 80 sandpaper (a little less would do fine).
