Input:
User Review: Hmmm, I just realized that this would have been the FOURTH time replacing this SAME can opener within the span of 5 year! I've read a few of the reviews and see now that the flaws in this particular opener are common!
The only reason I keep replacing it with this same one is because it mounts under the cabinet, up and off the counter tops..I think that's it's only quality! It no longer comes with a built-in knife sharpener..guess B&D figured they could make even more money selling a knife sharpener alone as a small appliance! The piercer that opens the cans quickly became dull to the point it will no longer open a can without force. IF I am successful in piercing a can, I have to hold it so it won't fall and again I have to force "walk" the can around as it will not make the revolution on it's own.
Can anyone suggest a GOOD under cabinet mount can opener please??
