With the Honor roll, we have essentially taken the teachersPet plus and made a few key changes. First, we've upgraded the projector to an ultra-bright, 2000 lumen model capable of projecting high resolution images. In addition,  we have conveniently integrated a document camera into the work surface of the unit. Any teacher who has the need to project 3 dimensional objects (e.g. open text books, petrie dish, etc.) can do so as easily as pressing a button on your teachersPet remote control! We have also included a locking drawer on this unit for convenient storage and access to your laptop or other accessories.
