Review on Portable Ultra-Thin LED Tracing Light Pad for Artists: A4 Light Box by Illuminati, USB Powered with Dimmable Brightness - Ideal for Drawing, Tracing, and Creative Projects - Includes Tracing Paper and Holder Clip by Rob Marsh

I like that the product is very light, easy to use and store. It replaces an old 24 x 20 x 3 inch fluorescent tube, so you can understand my excitement. It connects to a device with a USB port or to a USB outlet adapter (included). I see both possibilities. very convenient for us. One reviewer even suggested a power supply I could make. I like the clip too. He had me create a design for my son and give it to him as he knew the paper would stay in place. I found the best way to attach the clip is to start at one end of the box and slide it lengthwise into the box, just like you would attach a similar clip to a plastic report cover. plain 20 lb carbon paper on card stock. We used brightness level 3 in a room with the curtains drawn (sunny day). It also worked without darkening the room, but of course it was much better in a darker room. He was bright enough for that. Can't comment on durability as we just received the item but I'm happy with it. Note that the box (actually a tablet - you could hardly call it a box, it's so thin) has a tail to insert a cord instead of plugging straight into the box. There have been complaints in reviews of other products about the cables plugging into the boxes themselves failing and I'm happy to say there won't be any problems here.
