When my original NutriBullet finally gave out, (after 3 yrs of daily use, not complaining), I decided to upgrade to the NutriBullet Pro. I'm SO glad I did! It's great...blends up frozen fruit quickly and efficiently, and is quite a bit more powerful than the basic unit. This product is great!
Everything works great except that occasionally a small amount of grey-black grease goo sleeps out of the bottom of the blade attachment. Must be motor oil or something similar. Doesn’t seem to affect functionality so far; it has been about two months.
This is my second purchase of this brand. My last one the motor went after 3 years of daily use. I started juicing eight years ago with the first nutribullet. This 900 series is way better.
