My Mum has a Ninja and she loves it, and said it's the best blender she has ever used. I've used it at her's and I too think it's a great blender. The Ninja does everything as the Magic Bullet. But, if you really would like to get a Magic Bullet then get the Nutri Bullet instead.
I have the Vitamix and Nutri Bullet and they both are excellent.
Thanks eccles :-)
The reviews I've seen for the magic bullet are far more variable...lots of negatives re quality. And the vitamix is way out of my price range. I'd never use it enough.
This search was triggered by my desire to make my own coconut butter....funny how one pack of coconut suddenly expands to become another bit of kitchen kit. ;-)
