So we bought my daughter a Glowlight last weekend and she's quite happy with it. I was playing around with it last night and noticed there was quite a bit of darkness / weight variation in the text across the page. It looked similar to this effect jswinden saw on the Paperwhite only it's even more pronounced:
Is this typical of Glowlights, or do we have a defective unit that's worth trying to get a replacement for?
