Worked great until the RUBBER coupler between the motor and the blade sheared off while making a smoothie using frozen fruit. I should have paid more attention to the negative reviews of this product because they were absolutely RIGHT! This thing DOES NOT have an all metal drive as advertised right on the box!I used this thing for less than two weeks before it broke, and although it did a nice job blending, the reliability/durability just isn't there.Ignore these 1 star reviews at your peril!
