Query: Kitchen Aid Hand Mixer

We have been using a 30 plus year old West Bend hand mixer and, although it was still working fine, felt it was time to 'upgrade'.According to Consumers Report, the Kitchen Aid hand mixer was at the top of their ratings so that is what we ordered.I made a basic apple cake with the Kitchen Aid mixer and had problems mixing butter and sugar...they didn't mix well.The problem is in the design of the beaters, I think. They are basic wire, thin, not flared as on our old West Bend model. I visited a department store and saw the Cuisinart hand mixer has the same thin wire beater design.The Kitchen Aid hand mixer is being returned; back to using the 30 year old West Bend!
