I use mine all the time. One day after work, it was dark already and couldn't use the window, no lightsource after dark, so I made a light box out of some pine planks and a piece of leftover perspex I found in the shed, dismantled an old bedside table lamp and added a handle from an old attache case, so it's easy to carry. It's quite heavy though as I made it 10" high so my back doesn't hurt from bending over. It's probably the ugliest lightbox I've ever seen though. Did not even bother painting it, but it does it's job very well.
