Query: functional deficiencies

Pros - perfect size, simple to use, quiet, effective choppingCons -1) After my third use (total motor time perhaps 60 seconds and hand washed between uses), a hairline crack developed in the cup/base where a metal pin is molded into the plastic cup. I think this is a function of design and is unlikely just a freak manufacturing defect.2) The chopper is intended for use with liquids (it even has a liquid line on the cup/base), but with the least amount of liquid, it splashes up on the underside of the motor unit. This is very hard to clean. There is a little contact switch so that the motor won't turn if not seated on the base properly. Food/liquid always ends up there and in the drive shaft. The motor unit is not sealed underneath, so you can't rinse or immerse this.I don't have experience with any other unit, so I can't say what is better. But my suggestion is save your money and keep looking.
