The worst QC I've ever encountered. After I get mine back I'll be selling it for parts, with just 14 hours on it! First my "reconditioned" machine had to be returned because of problems with the crank system. Then it had to be returned because of "power fluctuation" detector problems. A new power supply just made the problem worse. Now CW won't or can't fix it. They won't return telephone calls. Wasted money, wasted time.
