This is my third nutibullet. I bought the Pro hoping for even more power to be able to crush up greens or seeds for smoothies mainly. The Pro works very well, but my only complaint is that it is very loud. I stopped using my previous bullet because it got loud and I thought it was the bearings were bad but this is a brand new bullet and it sounds just like the other one. My first two bullets never had this loud of a sound and this is supposed to be a better machine, so I’m a little disappointed with that. I’ve only used it for time since I bought it and I hesitate to use it much I have to walk out of the room and hold my ears in order to use the machine. If they could make it quieter, that would be a bonus.
