So far I love this! The motor is strong and mixes my smoothies even with kale no problem. I've bought other brands and all have broken or leaked within a year so I'm keeping my eye on this item too. I will update as time goes on.
When I needed to replace my older NutriBullet, I decided to upgrade to the pro model and am so glad I did. The motor is stronger and it breaks down nuts and seeds really well. A good purchase.
When my Magic Bullet finally gave out, I thought this was the next/better generation of the same. While the blades work a little better to blend things like kale and large chunks of ice, it's nearly impossible to open after it's finished blending. The cup itself is so wide I can barely get a grip around it to twist.
I both the 900 version 7 months ago and still use it most mornings. The only reason I didn't give it the full 5 stars is that the travel lid catch broke after not much use and my friend (who recommended this to me) also said her travel lid catch broke and this now prevents me from having it on the go as the other lid is two awkward. I don't feel I should have to pay for a replacement lid so soon!
