I purchased this light box for two reasons. First, because I needed a light source for foundation paper piecing quilting. It was increasingly difficult to lift up paper and fabric with any accuracy. I also copy patterns for leather stamping/carving. I especially like that the light itself is adjustable. I also chose this particular model because I don't use it a lot, so I really didn't need a rechargeable battery model. For the price, it's well made and can sit in your lap without getting hot. Before I even received it, there was a very nice email from the company explaining the warranty and encouraging me to contact them with any questions I had. That being said, I highly recommend it.
