The difference in our products versus others is the care we take in ensuring a near Original Equipment product. We do not "drill and fill" our toners. We do not re-use parts in our cartridges. We utilize the most well-known and established suppliers for aftermarket toner cartridge supplies. And we take pride in addressing any and all possible flaws with each individual cartridge component we inspect and/or replace. 90% of the components in our cartridges have been replaced. Each cartridge follows a strict pre and posttest, and rigid manufacturing procedures that have proven to result in the highest success rate in the remanufacturing market. If you aren't using OEM cartridges, your next choice should only be us!
