Input:
Until a week ago I would've told you this was a great egg cooker.  The alarm is pleasant sounding.  The eggs are done perfectly.  It's compact.  But it only lasted 8 months and then the knob on front broke off when I tried to turn the cooker on.  On further examination it was a bad design.  Instead of having the knob attached to a metal piece, it's rubber and it ripped.  I can't see buying another of this design.  My previous egg cooker had lasted over 10 years.  Disappointing.
