I have been very skeptical about the refil kits for ink cartridges to printers. It appears the technology has improved 1000% in the last few years. We bought a kit at Walmart for $9.95 and it filled two cartridges, black ink.
Our cartridges are $29.95 a piece.

IT WORKS....
I had to run a couple test prints to clear the smudges, hubbys didnt have that problem.

It would of cost us $60.00 plus (we both ran out at same time). Instead cost us $5.00 a piece ... saved $50.00
