I like these Leofoto QD-1 units better than any other comparable products from other makers. However, I'd like Leofoto to make a version that lets us open up the section where a strap goes through, so that we can use these QD-1 units with any of our favorite straps. At present, since these QD-1 units don't open up, I need to undo the stitching on my favorite straps, and put the QD-1 units on the straps, and then re-sew the stitching on those straps. Leofoto does a nice job of engineering many products, so I'm sure they can figure out how to engineer a version of this QD-1 unit that allows us to easily use these units on our favorite straps.
