My experience with bleeding is primarily from trauma associated with back country situations - lots of fractures, some open, major and minor lacerations, and one near amputation of an arm (which was later removed in the hospital). We employed direct pressure, elevation, and occasionally pressure points - right out of the then current FA book. We were always able to stop the bleeding readily - never had to consider using a tourniquet which I would imagine is the situation where Quick Clot would be most useful.

I asked a friend of mine working professionally as a paramedic if he had ever had any problems with bleeding (two plus years experience). No such events.

I don't think I will bother with Quick Clot. It certainly might be useful in a battlefield environment, but I doubt that it is necessary in more normal situations. I will use the space and money saved for more 4x4s and elastic bandages.
