I bought this about 4 months ago...and use it most often for the yummy fruit/veggie shakes which always come out very smooth. Just be sure to not overfill cup...then you may have problems with the machine getting most efficient rotation of blade. So very easy to clean.
We actually won our NutriBullet at our Credit Union meeting this last Spring & I had always wanted to try it. I have used it almost everyday except for Sunday (Chew-Day) & my husband and I have really enjoyed our smoothies for breakfast. Because of this change he has lost weight lowered his blood pressure & the swelling in his feet & legs has gone down to normal. We love it! My only complaint, I need his help getting the lid off.
Very good machine, feels like is gonna fly all the time :). I'll recomend to follow the instructions, base (extractor blade) doesn't last forever and you will have to buy them again (anything worn out anyway) also be carefull with the plastic tabs from cups. The blender is solid and powerful as new (after almost a year using it 2-3 times every day)
Have had my PRO for 6 months. Does a great job. Only problem? The screw on items, lids, blades, etc, do not stay tight if you are making a frozen smoothie. Apparently, after a few seconds, the cold shrinks the cup, loosening the threads and creating a huge mess on the motor, and spills if you tip the covered cup over.
