How good are those ink cartridge refils that you inject into the cartridge? worth it?

They dont work very good and are very messy. Go out and buy new cartridges. I found mine at Wal-Mart (at 11:00 pm one night).|||In my experience, very messy and poor quality. Spend the extra bucks for genuine refills from the printer manufacturer.|||if you want good quality colour id only use new or cartridges especially made by a firm for your printer.try www.inkworld.co.uk. find your printer and get their cartridges. they are excellent and very reasonable. A good service.|||Well it can be good or bad, the good thing is its ALOT cheaper, the bad thing is it may leak and damage the cartridge along with the printer. So my suggestiion woiuld be to buy the pre-filled cartridges since there are no risks.|||they aren%26#039;t because the cost about the same.|||They are very messy and using them may void warranties on certin printers.
