I love my NutriBullet, but if I could change anything, I would change the start application to a button or something easier. I bought one for my mother, and she has a hard time starting it.
I use it all the time for smoothies, drinks and recipes. The only thing I would change is to have it have a better grip on the blade, such as texturizing, because it can sometimes be hard for me to get it off especially if my hands are slightly wet.
The machine is no disappointment. The books are amazing, Although I could work through the drinks by myself, knowing which fresh produce works best with others was a real helpful starting step.
I purchased the product about three weeks ago. I have enjoyed using the product for preparing smoothies but I have a problem removing the extractor blade from the cup. Also the rubber ring inside the extractor blade has come out and I still have not been able to reset it properly. I am still working on the meal plan to see what works best for me.
The only problem I have is that the first time I used it the lid came loose an some of the liquid got inside. I cleaned it the best I could but now it is hard to press it down to start it to blend.
