I bought two of these. It's cheap plastic, but it worked fine for a year or two. It's very thin and not very wide. There's actually no cash in there, so I grabbed a money clip. They are not as good at branching out as the videos and photos make it seem and sometimes they get lost and confused. For $50 or whatever, it's probably not worth it. I switched to a Travex meter and have really liked it since the switch, even though it costs more.
