I've been using ninja blenders for as long as I can remember. First it was in restaurants then I finally got one for myself and I haven't used anything since. They are very well made and easy to use as long as you have the lid on correctly. This comes with a mini blender or food processor which is convenient for when I'm not make a huge smoothy or a ton of sauce or salsa. They are all easy to use and literally the top of the line. I would definitely recommend a ninja to everyone.
