We have owned one of these for 18 months. It has never done a great job of blending our fruit smoothies, but my wife wanted it to match the other KA appliances. Yesterday it failed, while trying to chop up some frozen strawberriies & OJ. I removed the jar & saw that the teeth on the drive coupling had broken off. Take a good look at the drive coupling. Its made of a hard rubber. This is going to be a failure point if you buy this blender.I would recommend loooking at another brand.
