I have used my NutriBullet for over a year now and absolutely love it. It works great for making smoothies, mixing and chopping kale, frozen blueberries, ice cubes and just about any fruit or vegetable to a creamy smoothie. My only complaint is that the plastic container is a bit hard to keep clean. I wash by hand and because plastic is porous, it seems to smell like fermented fruit when it sits between uses. I have to re-wash before each use. It would have been a better product if the container was made of glass as it would have solved this issue. Other than this minor problem it is an excellent product.
I use my NutriBullet 900 Series every morning for my protein shake (with ice cubes). It works in less than a minute then I screw on the handle and enjoy. Cleanup is fast and easy and I use the included extra cups with lids to carry other drinks with me in the car. LOVE it! p.s. I just bought the milling blade to make my own almond flour and almond butter but haven't used it yet.
I have been using my NutiBullet for a while because my other Bullet kept leaking. I returned it and found a 900 NutiBullet, which I bought. I can't say enough about my new bullet. I use it everyday and always have perfect drinks. I will never get a lesser power. I hope to use this Bullet for a very long time. I tell all my friends to only buy the 900 series. It's the best.
We bought the 600-watt 1 1/2 years ago for hubby's kefir smoothies to counteract chemotherapy effects on digestive system. We upgraded to the 900-watt this summer to make hubby's g-tube blends. (We did NOT want to rely on commercial "boxed" tube feed formulas!!!) I can custom blend his feedings to his daily needs, including cooked meat. We typically use the bullet 5 times each day. It has literally been a life-saver.
