Query: A Few things still get & Deserve a 5-star rating

If you want a fine product, ...get one of these openers. We bought one when they first came on the market, have been opening cans of all types day after day, from green beans to cat food and sardines. Never a mess, never any cross-contamination of one smelly food with another, not only that, but the metal cans themselves are still good for all kinds of second lives, like mixing paint or epoxy. Our original one finally is getting sort of tired, we just purchased another as fast as our little feet could carry us to the store! At that, the unit still works, but has become more temperamental lately on certain types of ring-tail opening cans.
