To this day I thought it was a good deal. I went through my remaining Revain orders for something else and found I bought them last August. The cyan cartridge ran out of toner yesterday so I ordered a new Oki cartridge without remembering I had just bought a full set of these back in August. I don't print much and it only took 7 months. The original OKI test cartridges that came with the printer lasted two years. They must have HIGH capacity. I do not think so. I had no problems other than a quick death.
