This is so convenient! I really like it. It’s nice that you only have one thing to clean rather than a blender and a cup. It has a tiny learning curve though. I usually add peanut butter to my smoothies/shakes and with this, you can’t put it in first because the blades won’t touch it. Another thing is that with the normal amount that I make for one serving in my blender, the nutribullet overflowed when I went to put the cap on to blend it. So make sure you don’t fill your container too high because when you go to put the cap on to blend, you’ll have a mess. All in all,  I will enjoy continuing to use this, especially when on the go.
