The directions and capabilities written on the box are accurate. The larger problem may be the HP OfficeJet 6700 printer. It will quickly rips through its capacity of ink, and then will not let you print, if it is running low. It allows the printer to warn you when capacity is low, but there are no workarounds, such as using dark ink for an emergency print job.
Therefore, I will typically have an extra on hand at all times. Again, the ink itself is serviceable and is probably the best I've seen for this model of printer, however being asked to review this ink is similar to being asked to comment on how shiny A crashed car is. Perfectly adequate, but also not the main problem.
