I used the nutribullet often until it started to smoke & smelled. I even found what appeared to be oil underneath the unit. Now, it just sits on my counter. What a waste of money!!
I bought this model a few months ago. Overall it is a great improvement in power and design from the base model. I used my last one every day for 2 years until the motor burned out so i decided to go for the higher powered motor. This motor is quieter and blends all my fruits and vegetables in less than 30 seconds easily including large frozen strawberries. The large container is a few inches longer but the max line is in the same place. This helps it blend better. The blade cover Is much sturdier. However the lid doesn't feel snug all of the time. I have seen the lid loosen up a few times while blending. I am not sure If I screwed it on crooked but it's not always easy to tell. I also like the extra drinking lid. It was worth extra dollars to get this model and would highly recommend it.
Purchased two nutribullets in July 2014. In October one stopped working and the other one extractor blade leaks. Prior to this happening the bullet worked fine.
I brought my first NutriBullet in Dec. 2012. Since then I have lost nearly 90 pounds and no longer take cholesterol, diabetes or hypertension medicine. I now weigh almost what I did when I graduated from college over 30 years ago and feel better than ever!! I purchased a 2nd NutriBullet last month so that I'd have one at home and another one with me in my car when I travel for business. Tremendous product that I've sold to numerous friends!!
I got this after doing my own research, it took me a while. The only thing I reject is not buying it earlier... My smoothies are healthier and delicious!! Never thought of puting spinach and/or kale in it, but nutribullet allows me to add more nutricious value to my smoothies. Love it!! Buying one for my elderly parents, so they can benefit from it.
