The UPD is a perfect device for getting the information that you need. There is NO way for anything
to fail. Those of us purchasing already knew what to expect so there were no surprises. The UPD can
just be slid into a credit card slot and you are ready to go. I had to work it into my wallet but
once it fits you are good to go. I have it in my Heirloom Wallet right now. It is a great utility
that has its place.
