I have never used these clamps and ordered them thinking they would fit my project. They really do - they are fantastic. Be sure to check out the pictures as they work exactly as shown. They don't work with very thick parts - you are limited by the length of the part of the clip that rotates. I order more as they are very convenient and easy to use. Yes, smaller clamps can get the job done, but they can be stored in a small pouch along with a bunch of others, and depending on the size of the project, you may need a few clamps to get the job done.
