I usually am very happy with this double pack. Sadly the last one I got I have trouble with the black ink not printing clearly even after the cartridge adjustment. Not sure what's going on. This is the first time.
This is the first time I ordered online replacement ink for my printer. This 2 pack is convenient, but I just wish the yield was higher. I didn't see the 901 come in high yield though. 200 pages is really not high enough so I ended up having to spend even more money to buy two 2paks. Each pack has one blk and one color cartridge. Having it shipped (very timely--within just a few days) is very convenient.
