The idea of paying more than $10 for a can opener took a while for me to wrap my head around.  Until one day I went to open a can.  I had 3 (yes, THREE) can openers and none of them worked.  They ranged in price from $5 - $8 each.  Finally I read reviews of this and closed my eyes and hit "add to cart".  It seems overdramatic to say a can opener has changed my life, but this thing is awesome.  It works the first time, every time.  It leaves a smooth cut and no jagged edges.  I've had it for about 5 months now and it works just as well as the day I got it.  It was a great feeling to throw my other 3 can openers away.  Those 3 cost more than this one, and I anticipate this one lasting longer than those did!  Welcome to adulthood, when you are excited about a can opener!
