Bests & Worsts Reviews from Amazon

First - Amazons Customer Service is amazing. I was sent two replacements after having issues with the first. Unfortunately, ALL three had the same issue - pink/green/blue hues over varying locations of the screen. I'm not talking about the "cones of light" at the bottom (which aren't bothersome) - these are clearly visible hues of blue/green/pink which comprise the entire screen, and are present from about 10 all the way up to 24 (in a lit room). Literally one sentence may be illuminated behind a background that starts out blue then turns to pink. It's very distracting, especially coming from the Nook Glow which didn't have this issue. This IS a 5* device, but the problem is so distracting it takes you out of the book..and no matter how good the cover/software are (they're great BTW) - that's a fatal flaw. I'm still within the return period, and frankly I'm struggling if I should keep this or not. I'm concerned that once this problem is fixed, will those of us with bruised units be allowed to exchange it for the "paperwhite" we paid for? Edit - I really feel bad for having to give this device a 1* review. The review I wanted to write addressed how nice having cover view is, how solid and well built the device feels, how spectacular the cover complements it and how worthwhile getting special offers removed was..because the "swipe to unlock" screen is gone, and you're brought straight into the book once the opened cover awakens the device. Quick and easy. I don't think the blue/green/pink hues necessarily justify a reason for the device to get reduced to 1* - but for the sake of alerting Amazon to the problem (and having seen three units with the same issues, + numerous pics from the mobile read forums), it feels justified - until Amazon takes further action to correct the problem. Edit (Oct. 16) - I received a very nice phone call from an Amazon employee today. They offered to either let me return this unit, exchange it for another (which would be my fourth), or make a note on my account and in a few months once the issues are resolved, let me exchange it for a proper unit. She reminded me about the one year warranty, and clarified that it would be covered under the defect clause, anyway. I'm satisfied. However, this will remain a 1* review so people who sort it will be aware of the problems. I'll update it once I have a proper unit in my hands.
