Review on Golspark Rechargeable Light Box for Tracing Board - Portable Cordless Light Pad A4 LED Trace Lights - Wireless Battery Operated Copy Board Dimmable Black Diamond Painting Sketch - Perfect Gift for Kids by Eric Miller

This light bar is well designed -- has 5 levels of brightness, is raised at the top, and the on/off switch is on the side and flush with the surface, so that it cannot be accidentally turned off or on during operation to drain the battery. It's also durable and feels very durable. I've often dreamed of a portable light pillow since I've used light tables in the past. If I had known there were cheaper alternatives, I would have bought them a long time ago. This lightweight mat is only slightly more expensive than others. It is excellent value for money and I am very happy with this purchase.
