Title: HP-40 compatible ink cartridge
Review: I bought 2 cartrisges at $20 each, they are not even worth 2c both together. After 1 sheet of plotting, the brand new cartridge started acting as if it's empty, missing line, shading etc. I have no choice but to thow away both cartridges and the $40 that I paid for them. I recommend Amazon.com to stop selling a defective item like this one. Absolutely piece of junk.
