I've been refilling my Lexmark and HP printers for years. The print quality is better with original cartridge. For the most part, I am not as color sensitive that it matters to me. With my kids and everyone using the printer, it saves me big $$$$. I use inksell.com (hp) and mrinkjet.com (lexmark) for my supplies. I have yet to have any leakage, spills, etc. The thing to remember when refilling is not to be impatient and not to overfill.
