my wife use it for enlarge artwork : she sketch at a convenient size , photograph the sketch , and the project the image onto a large canvas for trace . the device be handy and adequately bright to project a enlarged image in a well-lighted work area and be truly perfect for the application . the device ship with a simple quick-start guide , but the full manual be available for download from 3M ; have the manual be a comfort but it be really unnecessary unless there be a malfunction with the device . it would get five star except for a couple of negative : 1 -rrb- operation be intermittent apparently due to a bad battery connection ; however Amazon replace the original unit within five day of be notify 2 -rrb- while it support jpeg apparently there be jpeg and then there be jpeg : my wife use two camera , a Nikon SLR and a Nikon pocket camera ; image from the slr transfer via computer to the device with no problem , but image from the pocket camera give a `` format not support '' message . the workaround be simple , just run the image through any photoshop-like application to reformat it and it work fine but it be puzzling that the problem exist at all . as state in other review , this device be not really suitable for project presentation for group , but I would highly recommend it for any more intimate setting such as display of photograph to a friend -lrb- set it on a table and project onto a sheet of white cardboard work fine -rrb- and it be absolutely perfect for my wife 's art application .
