I recently started a clean nutrition program which includes two protein powder smoothies a day. One includes a banana and peanut butter so the shaker cup doesn't cut it. My big blender didn't seems to get the ingredients as smooth as I thought it should so I searched for a personal blender and based on reviews selected the La Reveuse Fit. It's perfect for my needs. Ice cubes disappear with a few pulses ! No pieces of anything , it's all a smooth mixture. I love it.
