I've seen some pictures of the GD-350 online with tilted (rotated) modules. Should this occur, is it hard to fix?
One of the worst I've seen is the picture of the GD-350-8 on Amazon.
I've had quite a few Casios that I purchased on Amazon (sold by and fulfilled by them) that were obvious returns with defects. I don't believe I've had this happen with Amazon third-party sellers so far.
