My wife brought me a CISS after lots of frustrating episodes with ink cartridges.

Prior to fitting I made sure my printhead was thoroughly clean with no blocked nozzles. The kit is complete and includes all you need and a few spares. Instructions for fitting via good quality YouTube videos that show and explain things very well. The fitting process took approximately 30 minutes and is very simple to carry out.

If you are having printer issues I would thoroughly recommend this kit, it is flawless when printing.
