I put this system on three of my guitars. This allows me to quickly change the strap and lock it from one to another
PROS:
Well built, good mechanics. Safe to use in extreme conditions
Comes in more colours/finishes, so it goes well with your other hardware
CONS:
The depth of the screw (that gets attached to the strap) was too small for my thick leather straps, so I had to overtighten it in order to work.
If you go for warwick, make sure your strap is not too thick and be ready to increase the gauge of the holes in the strap if necessary, with adequate leather-piercing tools
OVERALL:
Good buy, I'm happy with it
