Query: Worst can opener cheap or expensive

It opened cans OK for about the first month - I thought I somehow might be using it incorrectly when it didn't. It worked less and less reliably the more I used it. After about a year it took about 2 minutes to open a can - having to re insert the tooth into the can lid, trying to puncture all the spots it missed. Finally the arm broke off when I lifted it to inspect the tooth - never ever buying anything from Cuisinart again - that was my first and last cuisinart product.
