@Lech Where are you located? I’m pretty much in the same situation as you (stuck pixel, returned, supposed to wait 4 weeks for a new one) and now the music store is telling me it may not be eligible since there are two pretty major skuffs/dents on the side that were most certainly not there when I had it last. Not sure of the serial number as I no longer have the unit but I’m pretty sure we bought ours at a similar time.
@erthan I’m in the Netherlands. Indeed our cases seem similar, I wonder if there is an production issues with the screens on the latest batch?
I have taken pictures of my unit and packaging before sending it back, so I have proof of the state I returned it in. I asked for my money back, I can always order it again when it’s back in stock, no need for them to keep my money, the OP-1 isn’t exactly cheap
Your situation with the skuffs/dents sounds really annoying, I hope everything works out for you!
