This is a get down to business blender for heavy duty blending. Durability We choose this blender because my son required a heavy duty blender for making protein smoothies. This meant heavy duty ice crushing. This is a no fuss ON/OFF heavy duty glass construction that can take a beating. This means it can take the pressure of blending whole fruits fresh or frozen into your smoothies with just the right amount of ice cream or ice to make these taste professionally made. The glass blender makes clean up so much easier than plastic that can scratch and fade in the dishwasher. It is also hear resistant if you want to make hot recipes. With it's die cast base and stainless steel blades there are no plastic pieces to crack like my old bar blender. When that blender somehow followed my son to his new residence we bought the exact replacement model for my protein shake requirements due to a recent illness. Highly recommend.
