I didn't buy a new one. I got a replacement for one that died after 2 months of use. I still had to pay a shipping/handling fee under warranty. So far so good. We will see if this one lasts longer. My old one lasted for years. I used it yesterday and it spurted tomato sauce all over my kitchen as the gasket became loose. Never had this issue with my older model.
In short. They dropped the dry blade, (Very handy for some tasks) as well as the separate rim and smaller cups. They added a SLIGHTLY larger container and a re-closable lid
I use this everyday it's extremely easy and very convenient I keep it on the counter right by the fridge and in less than a minute I have a smoothie ready to go.
I recently started making protein shakes with tons of ice. The NutriBullet Pro works great - crushing big ice cubes in 1 minute. I like the size of the NutriBullet - not too big, sits nicely on the counters, tucked away. Also like the large cups.
