Somewhat disappointed for a few reasons, if you don't screw on as tight as you can it will leak out and I have weak wrists so I have to keep tightening and then it is so hard for me to unscrew. Also I'm just preparing for myself and both cups are too big for me.
It provides me the opportunity to have a smoothie that's not all full of air which fills my stomach up instead of the protein shake that I've made. Since I have very little room inside my stomach this is of primary importance to me. The only other thing I would recommend a sharpening the blades so that it cuts things up better and faster.
I have used a few blenders in the past two years to make my breakfast smoothies. Before finding the NutriBullet, I went through 4 different blenders. They all broke with in months. I thought the problem was not enough power, but even the 1500 watt one that I bought broke within a few months. I use a combination of frozen fruit and chia seeds, the NutriBullet is able to make a smooth blend. I have used my NutiriBullet Pro for a month now and it has been working well. I am hoping that this is the last one I will need for awhile.
I have had this for two weeks and I am using it every morning. Love the amount of fruits and vegetables I am getting in one meal. Easy to use and clean. No complaints at all!
