Purchased this in December 2014 and noticed a difference in 3 days!! Great recipes are available and they are all tasty!! So easy to use and clean. There are no complaints. Oh, just do not fill pass the Max Line!
I was a former user of the Montel Williams blender. Used it for many years, but it was a pain to clean and didn't seem like it was really mixing correctly anymore. I got the NutriBullet about a month ago and we LOVE it!!! We use it at least 6-8 times daily between myself and my husband. Great mixing abilities, super easy clean up!!!!
I love the idea behind the machine and for the most part it works well. However, I find that it does not pulverize fruit the way it does on television. For example, apple skin, pears and pineapples. Also, I have to grind my flax seeds because the machine won't do it.
Used the 600 rpm for quite awhile and then recently upgraded to the 900rpm and its is awesome! I make a lot of smoothies and this version makes them really smooth and in less time.
