The big benefit to these is that you get true mobility out of them. While holding a piece of work, lined up, in one hand, you use these quick grips in the other hand to secure the work. If it slips while clamping, it is still a one handed tool to release it, and reclamp it again. Enables you to maintain a professional flow to your work. I feel awkward when using regular clamps in comparison. They require two hands. You could use a spring clamp to hold it together, then get another clamp to give it a final hold, but the quick grip saves you from having to do that.
