I have a pad that can be used effectively for an Add a Number routine and is very fooling, but this
device is much more versatile. It allows for a whole lot of other routines, especially those that
change the content of a signed note page. The utility is very well made. The mechanics of it are
smooth and consistent. A few reloads are included, but it's super easy to create your own. This is
one of those devices where the phrase "it's only limited by your own creativity" is certainly true.
It's one of my new favorites.
