I left my review last night. I gave it 3 stars and mentioned I would have given 3.5 had it been an option.
I told about needing a replacement of my first PW due to the diagonal bands of light on the screen. And I did say that my replacement is much better, as it is.
But, since I know there have been issues with bad screens and bad replacements, I cautioned people to closely check out their screen since quality control seems to be lacking at this time.
I do hope Amazon will fix the problems soon. It's a shame to feel like your playing the lottery to get a good unit!
