Just got this CKSTBRTW20 kneading blade replacement and wanted to share my experience!
First off - it fit my 2017 Oster ExpressBake PERFECTLY. The installation was literally a 10-second job - pop out the old one, click in the new flat-shaped paddle. No tools needed.
The non-stick coating is LEGIT. Made french bread yesterday and the dough slid right off during cleanup. Big upgrade from my original paddle that always had crusty bits stuck to it.
But heads up - this isn't universal! Saw some reviews saying it didn't fit their machines. Definitely double-check your model number before ordering.
One weird thing: mine arrived with some minor coating scratches (not bad enough to return though). Works fine regardless, but QC could be better.
Overall? If you've got a compatible Oster machine, this $15 part beats buying a whole new breadmaker. Just saved me from tossing my trusty old appliance!
