It may be a little bit small but, what exactly are you doing with it anyway? It shows you exactly where the magnetic field is and it's very high definition version of this type of film. I bought two different ones to compare and this one is very good.

Don't expect too much. It is sensitive enough that with a bit of effort, one can make out the outlines of the magnetic stripes on a credit card, but that's the limit of its sensitivity. One annoying thing is the inability to "clear" it to either an all-dark or all-light state. In other words, it's about par for the course of magnetic viewing films.
