I was looking forward to upgrading to this blender but it’s really not good. First, the blade base design is huge and square, super awkward to handle, doesn’t have a lock in feature (scary). I absolutely hate using the personal cups even though that’s what I use a blender for most. The power is pathetic, no matter how long you blend you’ll have chunk greens in your smoothie..so gross. I regret giving my ninja away and regret not returning this in the 30 day window.
