I was so thrilled with something that would scrape without stopping the mixer.  Unfortunately you still have to stop and scrape because it will leave a wide stripe of unmixed batter around a point near the bottom of bowl.  I also had a lot of the white come off and I used mine a lot so it wasn't long before the rubber part separated at the crease.  So disappointing.  I love all my other Kitchenaid products and really was hoping for more out of this one.
