Actually I was a little (Eigent lech very) skeptical: one-tenth of the price of original cartridges !! They were easily and cleanly in my MX870 (which is not even listed in the compatibility list) use, and the result is indistinguishable from the originals: I've tested so far colored text prints on plain paper and A4 images on photographic paper and have nothing to complain about ,
About the durability (at least 4 times each cartridge is available) and the pressure yield, I can not say much at this time. Except that they will hold less long because I'm going to frequently print photos! The original cartridges I've always shied away from because of the MX870 is (it seems to me at least as before) a notorious drunkard ink and an extreme Saubermann (dressing the teeth before and / or after just about every "Malzeit").
