Any drummer who has played a live show knows the danger of having a floor tom leg slip out mid-set. I've had plenty of instances where a 16" floor tom comes slamming against my leg because the fastener came lose from the vibration. These memory clamps were the perfect solution to that problem.
As of this review, I've got memory clamps on my cymbal boom arms, my floor tom legs, and also on the rack tom arms to mark the specific height I like them at. Any touring drummer knows that time is of the essence in a stage change and you'll be lucky if you're comfortable with your hasty setup. These clamps save me literal MINUTES of set up time compared to when I wasn't using them and everything is exactly where I want it.
Gibraltar has a great reputation in the drum hardware industry for having sturdy, well-built products. These clamps are no exception.
Do yourself a favor: Get a couple of these clamps on your rig and you'll wonder how you ever did without. Great product.
