Query: Motor burned up after 3 months

I liked it for grinding up wheat grass in green Odwalla until the motor started spewing out black metallic powder and quit after about 3 months. Plan on using your warranty if any, if you go with this. The 600 watt Cuisanart best buy looks like the one I want to try next. That should be enough power and run longer than this one did.
