I have two, and have absolutely no complaints other than one issue with my own design, nothing to do with the craftsmanship. I shouldn't have gotten a suede-lined collar for my service dog's everyday collar. Eve's collar is like... five years old now? Still looks good, the leather is high quality and has softened up beautifully with no real conditioning. It's stood up to daily swims in saltwater, literally constant use, and no part of it has weakened and aside from the suede flattening out, it still looks awesome.
Thumbs up from me for the products I own. I can't comment on anyone else's.
