If you understand that it’s basically a Netflix subscription for ink, it works great, especially if you print photos it can save a lot of money. If you print a few things a month and suddenly go to 400 pages, you might run out of ink before the next set arrives.
When you anticipate running out soon, you have to give CS a call and ask them to send the next set of cartridges sooner than later.
Still, anything is better than paying full retail for refills at Cartridge World.
Because you spent $5 a month instead of $50 on cartridges of ink that will dry up in 3 months if they don’t get used. If you need an ink tank, then you aren’t worried about photo quality, in which case a laser is better.
