After waiting several weeks to receive this, this does NOT work. At all...It's just more of yet another. Very disappointed. Wish we'd read up on other reviews before ordering.

Ex Output:
Bad review

Ex Input:
Interesting book. A bit too much for me, though. The authors spend an excessive amount of time talking about their philosophical views.

Ex Output:
Good Review

I've had this mixer at least 8 years but I am not a heavy duty user as many other reviewers would recommend, maybe 4 times per month usually. The beater unit is no longer functioning after only 18 months. I'll probably order the same model again even though it gets pretty hot compared to others...This does make really great milkshakes and whipped butter with fresh fruit. The plastic cup holders are flimsy (I keep mine out for just one day in our kitchen) so be careful there.

Ex Output:
Good Review
