I previously owned the original nutribullet. After many years (4yrs maybe) of extensive use, it died. I decided to upgrade to the Pro simply because I could not imagine working out at the gym and not having a nutribullet to come home to. My only concern is, once you begin to use the machine, it begins to smell like something is burning. I am assuming this is because its new and maybe just burning of grease, or other, inside the motor.
I had an old NutriBullet and it did the job, but had started to leak. Got the NB Pro and what a difference in the power. As yet, I've only used it for my morning smoothies. I am very happy with it. My only complaint is I have small hands and sometimes it's hard to get the blade mechanism cap off.
We bought the nutri bullet pro three months back. It’s working really awesome. The only thing we are concern about is the Gasket, which smells really bad from the first day itself. We have used it only once or twice and packed the item. We want to exchange or return this model.
