Review on Ultra-Thin Portable LED Light Box Tracer: USB Powered, Dimmable Brightness - Ideal for Art, Diamond Paint, and Sketching - A3 Size 18.3 x 13.5in by Tara Ford

Changed from 1 star to 3 because the seller was great. They contacted me straight away - very nice people and willing to help. Fingers crossed the exchange works and I can change the rating to 5 stars. ---- It worked when I first plugged it in to test and the light was very bright, very good, but it didn't work. because the. The blue power light comes on, letting me know it's getting power, but the screen doesn't light up. The power button is touch sensitive, not mechanical, and it seems it just doesn't recognize touches. Maybe this is an intermittent problem and it will work in the morning, but I'm very disappointed. I will ask for a refund if I can't get it to work.
