Of all technology purchases we've made in the past five years this has been by far the best. It's ease of use and set-up has prompted us to recommend it to all our family and friends looking to replace home office equipment. We have never had any drum issues and it doesn't seem to use any more or less toner than other copiers we've had. Additionally, we have also experimented with using non-oem toners with great success. Ink/Paper Use We get the average number of copies/prints out of each toner. We have yet to have any drum issues and have had this particular printer/copier for 5 years. Durability As commented above, we have had this copier for 5 years - and it has been a great investment. We use it for all it's intended purposes - scanning, coping, and faxing. Also, we have moved offices 4 times and after each move it was easy to set-up. Design Since we've not had any need to replace this item I would say a fantastic design - in a world where technology is outdated in the matter of months.
