There is no denying that ring-pull or pop-top opening cans are convenient and this generally eliminates the need for any type of can opener. The trouble is they are still an obstacle for those who lack hand strength or suffer from arthritis. Most electric can openers should be able to open any type of can and this includes ring-pull or pop-top cans. Check the instruction manual to ensure the electric can opener you plan on purchasing will be able to handle all types of cans. Even if you are usually strong and healthy, we all have moments when we may be recovering from an injury or are just having a bad day.
