I really love Ninja Professional Bleander Duo with auto -iQ. It runs faster, only a few second I have a healthy smoothies for every morning. With 1500W it turns ice into snow in seconds. The personal cups are perfect for "grab and go" morning. The lid locking mechanism is top-tier, the blender won't even start unless the handle is clicked-down. The mahine is running with lower noise, so I can make smoothies and do not bother anyone. I love Ninja.
