I am swithering between a ninja 3 in 1 vs a magimix. Magimix seems to win in all reviews for longevity, sturdiness, parts etc. But I can't find anything that shows me for sure if I can use it to blend smoothies? The 3 in 1 seems to have the cup attachment like a nutri bullet, but I can't tell if the magimix does, and this is the deciding factor!
