Review on Postage Ink - Compatible Brand Postage Meter Ink Cartridge for IS280 Postage Meters; Non-OEM Replacement (Product # ISINK2 / Sure.Jet # 4145144H) by Gonzalo Marshall

I've bought about a dozen of these over the last five years and have always been happy. The price is about half that of OEM cartridges, so you can't beat it. However, over the past year I have noticed that the quality of these materials has deteriorated. I keep getting "Cartridge not found" and "Ink low" errors even though I've just installed a new cartridge. I got fed up and ordered an OEM for about double the price and had no problems. You get what you pay for!
