The unit appears to be functional, but there are some minor dead pixels on the screen display (you can still read the text/numbers without issue, but it's worth mentioning). We ran a stack of 26 single bills through it and there were no jams. Both pockets work on a basic level. With that being said, this unit has been heavily used, so it's probably best used for refurbishment processes. We did not test it in depth and don't know much about the product in general.
