I just got this today, so I can't speak to its durability, but it appears to be a quality cuff, like I've used in hospitals. The gauge is heavy, solid feeling, and has a strong clip on the back. The bulb and tubing are substantial, not flimsy, and the knob is metal and seems reasonably precise. The zippered carry-case is pretty much junk, though--thin fabric-lined vinyl with a cheap zipper and no strap, handle, or attachment points. It does the job of keeping the cuff and tubes contained (not flapping all over), but that's about it. Overall, a really quality item for the price.
