Like many other users, I love the shape, look, feel and power of this blender...I have used it less than a dozen times for fruit smoothies only...I start with plain yogurt and perhaps half a banana...I then drop in single pieces of cut up frozen fruit...after about 8 uses, half the plastic teeth were broken out...I continued until only one tooth remained. I called Braun and got a "replacement blade group" within a week...the rep said this new part had corrected the problem. Not so! I have used the new blade only once and one tooth has broken out.This Braun blender is a big disappointment.
