These cartridges are very inexpensive, especially if you buy multi packs. They're decent for most printing jobs, but not necessarily for true color printing of photos that you want to display or keep permanently.
The package is misleading. The "ultra-standard capacity" just means that these are standard capacity cartridges. I'm not sure what the "ultra" is all about.
I noticed that even though my computer showed the estimated ink level to be 50%, the printer was telling the computer that it could not print because the cartridge was out of ink.
Still, ounce for ounce and page for page, I think these cartridges are cheaper than the HP ink cartridges. I finally scrapped HP after getting tired of buying ridiculously expensive ink cartridges, not being able to print B&W when there was plenty of black ink, but no cyan; warnings that using third party ink cartridges voided the HP warranty; and having a printer driver that was flakey at best with Windows 7 (and Vista before that).
The bottom line is these cartridges are inexpensive, and in the long run, I think they're adequate for a basic printer (school projects, home office printing, etc.).
