Fast and easy to use. Clean up is quick also which is a great feature. Doesn't look like a lot until you start drinking it. Comes with recipe ideas and you can modify or make up your own.
Broke within a few days of purchase. I had another NutriBullett (600 watt) for a few years and didn't have an issue with it until it finally just quit working. Decided to purchase the 900 watt and was really disappointed. I've ordered another 600 watt NutriBullett which I'm hoping is here within a couple of days. I usually use my NutriBullett 4-5 days a week. Really enjoying having it "ready to go"!
Love the design of blending in a to-go cup. One less thing to clean. It's great for personal use but since it's small it's not great if you need to make something for more than 1 person. Also the caps design isn't great. You can choose to use the only one with a cover that doesn't have a handle and makes it hard to grab (it has fallen out of my hands a few times), or the one with a handle but no cover, which is bad for rainy days. Also the clips on the base that activates the blades sometimes get stuck if you get any food in there.
This is my second NutriBullet, I wore out my first one after several years of daily use. I opted for the Pro with the more powerful motor and larger mixing chamber. I'm enjoying it.
For the most part I enjoy the ease of blending with this machine but I'm realizing that I still have to chop down some of the food into smaller pieces. Some of the pieces get stuck at the bottom of the cup when blending. It's also very noisy but I'm satisfied about the ability to make smoothies when I need them.
