I can thoroughly recommend one, it is an excellent way of getting your daily supply of vitamins, mineral and antioxidants. I have one about four or five times a week.
Had a cheapo blender last year but it broke due to high usage so when I saw a deal for the nutri bullet I bought it to replace. I would recommend it though, blends quicker and higher volume, really good with nuts as well! I don't really go for the nutriblast thing, I just blend what ever I have (usually frozen berries, orange and celery) also use it for soups,sauces, dips, grinding and making milkshakes... Use it pretty much everyday as well
