If you bought a Das Ultimate then I believe you're in the safe zone. You can double check by flipping your keyboard over and if the bottom says "Made In Taiwan" then you're in the clear. It's like people said the hate probably come from the gloss finish and the change of OEM.
The gloss finish is more like love and hate, you either love its beautiful finish or hate the scratches. Personally I own a Das MX Brown and I think it's awesome. My daily driver is a Filco MX Red but I'd say quality wise they feels very close.
The OEM change however is pretty much the deciding point. I think geekhack has a general hate towards iOne products (Razer Blackwidow) for their poor quality control. So people are worry about things breaking down if anything. Das used to be with Costar which everyone love here.
I bought my Das during their Costar era and I still loves it.
Das used to be the go to board for people who just got into mechanical keyboards since it has proven quality (Costar) and is cheaper than Filco.
Nothing wrong with Das, besides the fact that most people here have stopped indicating it ever since they changed their OEM to iOne. And that includes me.
Yupe keyword is
stopped. I used to recommend Das, just not anymore.
