These do a single job, and they do it well.  They just work.  My reason for dinging them a star, is that I've Seen the Planet Waves adapters, and Hosa's stuff is just not really as polished and nice.  These stick in some XLR males (in direct boxes, for example), and really have to be pulled/wiggled out with effort.  Normally that wouldn't be a problem, but the release buttons are really tiny and pointy, and you have to press them crazy hard to pull them out of any panel mount connector.  Plus the finish leaves a bit to be desired, although over all that doesn't matter much.  In short: if you need them, their fine.  They could just be more classy in their physical design.
