Go here to get some info that might be helpful to you. I love my Magic Box with my Janome machines...Good Luck! You might also want to google it to get more information, if needed... :-)

I loved my magic box that I used with my Brother machine. I've since given the box and the machine to my sister, and upgraded to a Singer, but the box worked very well for me. Make sure you have a port for the magic box on your Brother machine before you agree to the deal, though.
Blessings,
Diane

I love my magic box use it with my bernina 739.

the allbrand site pretty much sums it up good... I like my readers and the fact I can plug my computer in to my machine as well as USB flash drive...modern technology is gr8t...how did we manage without it for so long...:0)Good Luck
