This NutriBullet Pro appears to be an interim step to the NutriBullet Rx. Really wish I'd waited. My original NutriBullet was very simple to screw on the blade / lid and I never had a problem. This blade system has a gasket that separates if you screw it on too tight and will leak if you don't.
Have used for 8 months. Motor burnt out. Not even worth trying to get usettled warranty from what I have read. Loved it but very expensive for 8 months of use only. Will probably try another brand.
I have lost 30lbs since July using the wonderful recipes and drinking a smoothie a day. They are as well very healthy and helped me to lower my cholesterol and my blood sugar. One of the greatest item I have ever purchased. Give it a try. It's worth every penny. I promise you.
Don't get too excited and twist the container too fast. You will find yourself spending hours disassembling the machine to remove the container tab under the white spring loaded tab. Ugh. Great YouTube on how to do it.
I like the nutri bullet okay but the one major flaw is that it leaks. Even when only partially filled, the seal becomes loose and your smoothie leaks out. Then the clean up is a hassle. And this happens often. If it weren't for that, I would rate it 5 stars.
