Query: Works good, does what its supposed to.

Great product, does what its designed to do. I use it with a heavier/larger vivitar flash, wireless trigger combo, and umbrella, and everything works great together when attached to a backlight stand.The one little flaw is the screw that holds the flash in place could be a little more heavy duty. It seems that if I were to put to much force into tightening it, it would strip the threads pretty easily. My flashs have a lock switch on them anyways, so I don't use the screw on the clamp that often, but thought it would be a good idea to mention it.
