bilig? I do not understand!

I bought despite the bad review bezgl. Of cheap processing this alarm, because I like the functions a lot of sense and appearance was pleasant after a long search for the "perfect alarm clock". At the advertised price I would have taken even "cheap processing" in purchasing. To my surprise, but that is not the case. The alarm clock is very difficult, is safe and stable. He clearly is plastic. But you knew that beforehand. The plastic is neither cheap nor unstable to me - on the contrary. The function of the two alarms and the simple slide switch function is great and the very clear the display. Even without glasses, I can see the time at night thanks to good lighting fast, that did not work with my old alarm clock despite light.
So I do not understand such a poor rating all ... if you do not want plastic alarm clock, one should perhaps not buy? Or at least only deduct one or two stars instead of making all the alarm bad?
