Saw a creality ender 6 on discount at fnac.com (in spain) and got it. Arrived, straight away noticed the blue side panels were COVERED in scratches. I can see the other parts have signs of (at the very least) being assembled. there's some brown kind of powder or something similar on the belt.

The company that sold me it have been stating for weeks that the scratching on the doors is normal and happens in transit, which I don't believe one jot.

However, I did read somewhere that these printers get pre-aseembled and tested; but I just don't trust a thing these guys are telling me.

I've told them to discount me 1/4 price if they want me to keep it
So:
1. are they right, and it's possilbe it's new; but has scracthes from transit to europe and was pre-assembled by Creality for testing
2. should I just keep it?
3. Should I insist on a refund and keep it?
4. Should I insist on returning and buy it elsehwere, no matter what?

Thanks for your insights.
