While slick looking and a great idea the laser pinter required batteries which were so hard to install that most speakers (who received them as gifts) gave them back to me. There is a tiny screw in the laserpinter part of the device that - unless you have a tiny screwdriver handy - you could in no way access. I thought that perhaps a little screwdriver was included but it was not. I am now sitting on 500 of these things and have no idea what I'm going to do with them. Dreadful product.
