Review on Efficient Replacement: F-INK Empty Refillable Ink Cartridge for Brother LC201 LC203 LC203XL, Compatible with Brother MFC-J4320DW J4420DW J4620DW J5520DW J5620DW J5720DW Printers by Gary Haymon

Bad I wish I put on gloves to do this but that was my fault. It was easy, just charge and go! I was a continuous ink system user, but after one wipe I couldn't get rid of those bubble lines no matter how much ink I put in. This has been fixed and is ready to use! Over 50 color pages printed on both sides and still in good condition!
