I bought this mixer to replace my Kitchenaid hand held mixer. They were both about the same price but the KA did not have enough power to mix a stiff cookie dough.  I really like this one it gets the job done.  One small concern is the lowest speed is pretty fast so you have to be careful when you first enter the bowl or you will have a mess.  If not for this I would give it 5 stars.

Pros: Great motor strength and speed, gets the job done quickly
Cons: It's speed is pretty fast but not really a problem.
