I don't do a lot of printing and sometimes my cartridge can last me six months, (ignore what they say about it drying up!)

This is a cheap alternative and is still the genuine thing. I bought this back in September and have done maybe 100 black and white pages, labels a bit of the kids coursework and hundreds of music note sheets and its still showing as nearly full!

Easy to install and use. And a top tip dont rely on the reading try cleaning the nozzles and changing the colour of your prints to a dark grey and you will usually get a load more ink from your cartridge!
