reliable clamp, no slipping when used with heavy items but for acoustic toms its worth having memory locks to stop slippage over time. Can't buy better really in terms of manufacturing quality. have to add that even when used with my e-kit I would still use clamp on memory locks. The chrome finish does not easily tarnish and I can say that if used on drum rack ends you can pop off the plastic pipe caps and with these clamps you can insert cabling inside the pipes because they allow full access to the pipes interior. This has been using for subtle hiding of trigger cables when e/acoustic/hybrid kit is used for performances or just tidying the floors or rack space. These clamps are really tough and take some punishment-you can use them for so much.
