I use my nutribullet almost everyday and it is great. If you make a smoothie I suggest you wash the blades immediately otherwise it can be hard to clean. Overall, I am very happy with this purchase.
Bought a year ago, needed to wear ear protection if you stand anywhere near the unit. Now the blade has started to smoke like there is no oil in the bearing??!!
I love my Nutribullet Pro 900! It is so easy to use and effortlessly emulsifies raw leafy greens and fruits into a drinkable and palatable smooth consistency. Also, this is my second purchase; I purchased my first one back in December 2014 and it withstood 5-days/week personal usage for over 8 years.
I have been through three gaskets now and have discovered that the problem is me using nuts, when the advertising clearly shows and states using nuts is one of the benefits of the higher wattage unit. I do not recommend this unless you don't use nuts, maybe avocados - those were in some of my smoothies, too.
