The best thing about delsan is that it can be used for any office equipment, not just printers! It's cheap but still very good at what they do.
I wish there were more options to customize my cartridges like with other brands; however this doesn't really bother me too much because i'm using them mostly from home anyway so if anything happens then its no big deal. If you're looking into getting some new printer ink or laserjet/laser copier paper try out these products first before going ahead…
