I received this can opener a few days ago and it works great.  I was skeptical at first because the detachable can opener head is partially made of plastic, not metal, and I wasn't sure it would stand up to extended use.  So far it is doing fine.  

I really like that fact that the head is detachable for cleaning - this makes cleaning it a lot easier.  And it's really simple to detach and reattach.

One part that surprised me were the extra features - it has a built in knife sharpener and an "Open Mate" which opens bottles, pop top cans and cuts plastic packaging.  I think the Open Mate may be my favorite part of the can opener!
