I’ve had no trouble with this bowl. I love that I can see everything that is mixing and make sure it’s all mixed without over mixing. On the box it tells you that you may need to change your mixer to a higher setting and exactly where to find the instructions in your owners manual. It’s as easy as turning a screw on your mixer. If you lift up your mixer there is a small screw under where the two pieces meet. Turn the screw counterclockwise to raise it or clockwise to lower it. If you do that, you will not have any issues with your paddle from hitting the bottom and breaking the bowl. I hope this helps someone.
