It's a work horse, but after running for a bit you can hear the engine weaken ... 30 sec maybe? Otherwise it starts off strong *every* time. My other complaint is constant leakage. I wish they had bigger containers available. Nonetheless I use this nearly every day and it is now a reliable staple in my kitchen.

I bought my first Nutribullet in June to assist my homemade smoothie diet. It was so successful that I bought a second Nutribullet for our mountain home and a third for work. I have lost 92 lbs to date on my way to 160 lbs. two Nuribullet smoothies a day keeps all the doctors at bay!! Great machines!!!

After many replacement blades on my 1st model of the 600 because of leakage, my 600 died at about 2 years of age. The inside had rusted screws and much grunge from the leakage. I took a chance thinking Nutri Bullet must have surely made improvements since my first purchase and I bought a 900 only to be very disappointed within 1 week, by the same problem of leakage which means this one will also die before its time if I don't throw it away first due to extreme frustration of having it leak so much, making a mess that leaks into the machine. I have to turn the machine upside down stuffed with paper towels to help it dry out. Aside from the horrible messes I end up with, the 900 has good power. but this is so, NOT right...

I used the previous version of NutriBullet for several years and loved it, but now I decided to upgrade to a stronger version. EXCELLENT machine indeed ! A bit bigger size of the cup is very good too since I'm making smoothies for two people. I love to REALLY load it with different veggies & some fruits, as well as adding chia, flax seeds, nuts, etc. and these heavy smoothies are easily replacing our lunches. And another thing - the size of the machine is perfect for the counter-top even in a relatively small kitchen. Actually, I have recommended this machine to quite a few people already and will do it in the future as well.

I bought this about a month ago, and let me tell you I just LOVE it!! It blends spinach, nuts, frozen fruit, ice perfectly !!! It performs exactly as it is stated in the description of this product. YOU CAN'T GO WRONG WITH THE NUTRI BULLET PRO!!

Loved the way it made juice but quit working in less than a year. Got a new one in August and then it stopped dead in October. Too bad. I really enjoy making my own juice but am leery about get another one or any of the other brands that you have to push down on to start them.

I love this product and have had it for close to a year. Unfortunately, within the last couple of weeks, a problem has arisen in that the "tabs" that push down to activate the Bullet are "stuck" and won't push down. We've worked with it and have thus far managed to "unstick" them, but it's annoying, unexpected, and not sure how long this will continue to work. I would have rated it a 4 or 5 star except for this issue.

Cup sizes provided worked great for varying between a full meal shake or just a snack. Plastic is good and durable quality. You have to run this in PULSES...holding down on the cup to run the motor causes the unit to heat up quickly. Cleaning is easy, just running the blades under water after use removes everything.

I just returned from a 3-week trip on which I packed my NutriBullet Pro/Medium Cup/Blade. It didn't take up much space in my bag or the hotel room, it was great to have it along, and grinds like a beast. I use it every day at work. It grinds up frozen fruit like a boss and it makes protien shakes about 1000% more enjoyable to drink. If you are on the fence about investing in this product, get off. Buy one, you won't be disappointed.

My first Nutribullet was the 600 watt model. I had it for about 5 years! Remember when I bought it from the infomercial! But I guess after making preworkout and postworkout smoothies almost everyday, I wore out the motor. Now I am decided to go for the 900 watt model. Hopefully it will last me years as well! Absolutely love it!
