We're very happy with our Nutribullet, we used to have the GNC similar blender, and simply Nutribullet is the best!. We use it for our protein shakes and smoothies!
I was really looking forward to loving this unit. However while mixing it leeks from the cap. I bought the extra one too to give as a gift. After talking to a coworker that owns one she stated hers leeks as well. Plan on going toace hardware tobuy that leeking white tape. But for now it's back in its box.
I bought it a month ago and it is really helpful for my juices recipe. Easy to clean. I just think that if the cups had mesure marks would help a lot. I still beat eggs on it.
