I bought these without realizing that I could make my own out of rubber tubing available for like a dollar a foot somewhere local to me. And I could make them the size I need.But having said that, these are alright. If you don't have a place that sells rubber tubing for cheap, this is probably a fine substitute. They're a bit short though. If you have pickups that you mount kinda low, you may need to use 2 on each mounting screw for added support, lest your pickup flops around and generates microphonics. No one likes a floppy microphonic pickup...
