The Key Ring-Go Hub does exactly what I expected it to do. My keys are separated, and no longer get tangled. It is light weight, durable and keeps my keys ready to use without any hassle. It was a wonderful purchase. My wife is eyeing my key ring and it looks like I will soon be getting another for her. In a word, this thing is "PERFECT".
Most likely be using this on a "zinger" for fly fishing. I dig the design and concept for keys as It was intended for, just made mine feel awkward. However have already found several applications where this bit should be very beneficial.
