I have a NutriBullet 600 and used it happily for over a year. I bought the 900 because I wanted the monster cup which I couldn't buy separately even though I was told it would fit into the 600. I had many problems with leakage around the outside edges of the 900 and had everything replaced. It is still tricky to keep it from happening again. I do not like the film which I can't get off the plastic monster cup. I was told to use vinegar. Still doesn't work. Never had a problem with the cups that came with the 600. I am seriously considering the Ninja on my next purchase.

I bought this because on the commercial my husband saw and it shows how easy NutriBullet i900 makes juice out of everything and cleans up quick. The mouths of all of the jars have the same circumference, so you can screw any lid onto any jar. They fit well, as do the blades. It took less than five minutes to get the NutriBullet up and running. Screw them to the top once you put in your ingredients, flip the whole thing over, and put it on the base. Then, you can push down to pulse or push down and turn it clockwise to lock it in the "on" position. We liked the ability to leave the NutriBullet blending continuously without holding it down. However, after a owning this for five months now, the blades of the 900 is no longer sharp and not braking down hard ingredients such as apple and carrot and can’t believe we have to replace the blades already. We are not totally satisfy with i900.

I'm very active, I exercise almost daily and I like to keep busy. Before I had purchased my NutriBullet Pro, I would get fatigued. I would eat energy bars, veggie chips, etc. and get 7 to 8 hours of sleep. However, I wasn't reaching my energy potential. Therefore, I start drinking shakes with pecans, fruits and green leafy vegetables and I notice the energy boost. It's been 2 months and I look and feel great!

I bought my nutribullet 6 weeks ago. I am a financial advisor and I run a different schedule every day. I am not good at eating fruits and vegetables on the run. I started using the bullet every morning, half fruit, half veggies, protein powder, sometimes pecans, cocoa nibs, flax, chia, I even throw my big osteochondroitin tablet in. I was really not expecting much, but it has been a game changer for me. My energy level has increased and my brain feels like it has changed me out of a fog. I have not been able to give blood for over a year because my hemoglobin was always below the required 12. I went last week and it was fourteen! Thank you for making good nutrition so easy and convenient! Margit J. Lund

I got my bullet about 6 months ago to mix up my shakes. Within those 6 months I've lost weight and I'm getting all my vitamins that I need & want in my diet. When I would use a normal blender my fruit would not be chopped or mixed up like using the NutriBullet. FANTSTIC INVENTION!!!

I've had this for a month and it is my absolute favorite! I feel like it is inspiring me to eat healthier. I get really excited when I'm getting for work and I get to try a new combo of fruits, veggies, and Greek yogurt. The blending takes no time at all and I love that I can just screw on a lid and go when it's done. Very much worth the investment.

We bought this product about three weeks ago and use it almost daily. We have found that sometimes liquid leaks through to the rubber gear on the bottom of the blade shaft--not sure why. (And only sometimes.) Still, we love it and would love to know (1) how to prevent the leaking and (2) how to clean the bottom of the blade shaft after a leak. We tried, but it smells a little vinegar-y now.

I asked for this for Christmas and did not know much about it. I began reading the info that came with it and became really charged about possible meal replacement to keep weight in check. The fruit and veggie shakes are filling and are helping me manage my food intake. I feel like I am getting much better nutrition by making a daily blast for lunch. I am sure glad I asked for this and will continue to experiment with combinations of fruit and veggies. My digestive tract is working better after just 4 drinks! This is the best way for me to add low calorie food to my daily intake.

I have had my nutribullet 900 for 3 weeks now and I use it every single day. I am not a vegetable eater, but now I have spinach or spring greens every day in my bullet. I have lost 11 pounds in 19 days without adding exercise-just wait til I add that too my routine. I can put frozen fruit in with no problem-it is an amazing product. Would definitely recommend it to anyone!

I was surprised to find no rubber o-rings for this one as my Magic Bullet had them, however it makes it easier to clean. But it tends to leak more and it's hard to clean the insides of the motor base when that happens so after a month, I couldn't get the bullet to click in place to activate the motor. Had to take the base apart using a screwdriver and clean the insides, was so tedious and time-consuming, I'm afraid to use this now! Ability to grind and make smoothies in mere seconds was a lot better than the Magic Bullet though, very powerful. Also made the best chocolate mousse with this!
