Negative Positive
Title: Poor engineering
Review: The white plastic teeth and plastic drive mechanism are truly a bad design. Have sent back three of these blenders, and finally gave up. Two had broken white teeth, and one of those had a motor "grinding" sound like it was under a load it couldn't handle. The third had broken white teeth and the black plastic drive mechanism the teeth fit into on the base also broke off. Did not put any of these machines under difficult stress, but was mixing smoothies, with frozen fruit pieces. Added the ingredients slowly, and if the motor started to accelerate, stopped the machine, added more liquid, and resumed. But, each of these machines tolerance for significant frozen loads was really grim. Consumer Reports really got this item wrong, wrong, wrong. Our $15.00 blender from WalMart works better!!!
