There are large spaces between the walls of the pitcher and the blades, meaning food gets stuck there and refuses to blend. It takes forEVER to blend anything (and by the end it isn't even that well blended) because everything gets stuck in the sides and you have to stop the blender every 20 seconds and try and push it with a spatula towards the center. Also, the top does not attach very well and would slide upwards; you have to hold the top down the whole time to make sure it doesn't get pushed off.
