The sette 270w they sent me to review had a problem where it stopped working. I cleaned it out and removed the burrs, no issues to be found. I called Baratza and they took it off my hands to be repaired while I was on vacation in Switzerland. What happens next is stuff of legend, i think they want me to review the standard sette 270 because they sent me one. Then my sette 270w came back as a sette 270wi they had to replace the gearbox, it had slipped a gear. So now I have some new grinders to review and the 270wi is much quieter than the 270w, I'm not sure what they did.
