This 'defect' you can also see in the youtube video below ...
Thanks, I think you're right. The dark stroke / mark above the right arrow key is clearly visible.
Just because it --came-- like that, doesn't mean it's not defective..
Fully agree. I'd expect a $200 plus keyboard to be flawless.
Don't bother sending it back, You even said you can only see it at certain angles/lighting, and there's a good chance you'll receive another one with the same mark.
It is very much noticable on my black Realforce in the afternoon, when the sun shines from the side onto the keyboard. The scratch strongly reflects the sunlight. Looks like a thin, silvery line, or a hairline crack. Trust me, it's annoying.
Still considering if sending it back from Europe to the US is worth it though, as it seems I will have to pay for shipping.
