In addition to the smaller cans, our family uses a great deal of #10 cans. These are the big cans from Sam's Club or other stores that sell the bulk goods. We average about a can a day. They can be a bit rough on normal can openers. The electric one I had last the longest was the Hamilton Beach 76606Z Smooth Touch Can Opener, Black and Chrome. It cut through the can and left a smooth edge safe for my children. With the #10 cans, it lasted a year. When it stopped cutting #10 cans, we were able to still cut the smaller cans for about another year. I purchased another and kept one labeled "Small Cans" and labeled the new "Large Cans." It seemed to be a good system but when I purchased the third, it stopped working rather quickly. The motor seems "sluggish."
We had one of these in our kitchen pre-fire for over 10 years. I purchased it from another company about 15 years ago, and it was $60 then. I like this one better. It is made better, sits so the blade is protected from contact, and has a rubber piece that makes it quieter to use.
It is heavy, but you only lift it enough to slide the can under it. If you are able to lift the #10 can, you can lift the can opener. The metal plate helps protect your counters from the big cans. Mine is mounted on a rolling cart. My 10 year hold has no trouble lifting it or turning the crank. Clint added some food grade grease to the gear mechanism for easier turning. It took less than 30 seconds to install with the provided screws. It's not a portable can opener for on the go families though.
*Food Service and restaurant supplies are great ways to find items for your large family kitchen. Those items usually are well worth the money. There are some suppliers that say they won't take small orders, but when I have explained my situation (busy mom of many who cooks nearly all of our meals and frequently cooks in bulk to save time, money, and clean up) they were more than happy to relax that rule for me. It never hurts to politely inquire.
