This motor is awesome. With proper gearing, it runs cool, even sounds great and just performs. I'm very happy with it... not to mention, it's very handsome.

Side Note: I'm using this on a Synergy 516 which uses a different shaft. Installation of the shaft was easier than I thought. Although I didn't find any how-to videos, it's easy enough for the average hobbyist with a mechanical press to figure out.
