Query: Elegant design and function.

I bought this quick release adapter to attach to my Slik SBH-320 ballhead. Compared to my experience with the quick release mechanism of my Manfrotto 141RC tripod head, I found the QRA-635 very unobstrusive. The very slim QR plate when attached to the camera never gets in the way when I stuff my camera in my bag, so the plate remains on my camera 24/7. I like using it so much that I bought extra plates for my other cameras. The likewise slim design and light weight of the adapter itself makes it seem to be an integral part of my ballhead, that I usually forget it's just an adapter. Mounting and unmounting the camera to the adapter is fast and simple. Once mounted, the camera (a DSLR) is held securely. This is one very admirable simple gadget.
