Owned a Blendtech prior to buying this Ninja. For me personally there is no comparison between the two different brands. This one is I feel much better in terms of blending, crushing ice, and quieter, I know the cutter/mixing blades are much better and it does a quicker job of making smoothies. My unit has multiple attachments including the two smoothie cups which I really like! Ingenious idea making them as a single serving blender. I’ve had mine a month now and I absolutely have no complaints with it to date. Very satisfied!
