I wondered a little at first: was the price saving compared with a new HP toner cartridge too good to be true? Well it was good, and it was true: well below half the cost of the new HP product, prompt delivery with adequate packaging, worked well, did the job. And a happy feeling of having done something (however small) towards recycling and the protection of the environment (there's a lot of plastic in toner cartridges, I never liked the idea of their being used once then dumpored). What more is there to say?
