I bought the equivalent from Aldi (or Lidl, one of them anyway) a couple of weeks ago. Much cheaper and does the same job, it's great! £14.99. They only had pink, which upsets me, so it gets hidden in the cupboard when I'm not using it, but I'm really pleased with it! It may not have quite as many accessories but it's perfectly adequate, especially if you're not sure you're going to use it much.
If I was buying one myself,I'd get the nutrininja. I've got a Ninja blender,and a Ninja food processor...and I'm very happy with both.
But...since it's an item that *may* end up at the back of a cupboard,do have a look at Aldi's version.
Then again, when the Mail tested them, the Nutribullet came out top.http://www.dailymail.co.uk/femail/food/article-3395410/Can-Lidl-s-29-version-Nutribullet-compete-80-rival-FEMAIL-pits-thrifty-gadget-against-original-REALLY-delivers.html
