Query: Durable But Designed To Be Obsolete

In spite of all the positive comments for this mixer, it is designed to be unrepairable when it fails.We have used ours for 10+ years, but now the mixer unit won't hold the beaters. It is still functional otherwise, but is constructed so that nothing short of a small explosion or a secret latch would allow you gain access to the internal workings for repairs.I know, I know, you'll tell me not to expect more from a modern appliance, and that the case is designed to be waterproof, etc. But the fact remains that two pounds of motor and polymer are now useless due the failure of one small plastic part. Consequently, we'll look elsewhere for a replacement.
