I use two of these - one to attach a leather strap to the headstock of a accoustic dreadnought guitar, and another to attach a strap to the headstock of a concert size ukulele.
It works fine for both of those :)
Looks nice, especially paired with a similar coloured leahter or suede strap.
Seems secure - I haven't had any trouble with it to date.
For me it's worth the price.
