Basically, the reason HP replaces the nozzles with each filling is because they wear as ink is forced through them. Worn nozzles equals increased ink flow (consumption), which in turn equals poor print quality and higher ink costs (more frequent ink exhaustion). In addition, the worn nozzles can allow ink leakage, which will damage the printer. For a gross example of the wearing effect of flowing liquids, just think of the Grand Canyon...
The ink quality is not likely to be anywhere near OEM quality, meaning that it will likely either dry out in the tanks and nozzles, or else smear on the paper (drying too slowly). Ink drying in the nozzles leads to additional ink usage in the cleaning process as well, which is great for the folks selling the refill ink -- they get to sell you that much more!

I have refilled cartridges with great success although only normally get about 3 refillings.It is a very clean and quick operation. In fact I have a Canon black cartridge I must have refilled about a dozen times and it still works well. I have for a very long time used compatible cartridges for my epson and I can get 2 colour and 2 black for about £8, but I am talking of an english companyThe compatibles are every bit as good as the originals with no problems. I don't refill as much these days as the compatibles are so cheap. John
I have a HP 712 printer, 4 years old and have refilled the black cartdridge a #61545 , 4 times with ink from Mazels which is a ODD LOT type of discont store, The color cartridge is the original.Everything work very good, no problems...
Best bang for the buck is Stratitec InkJet Refill kit from Sam's Club. I use it on my HP PSC-500 with good results...getting 4 - 6 refills per cartridge. And it's the easiest, no mess - no fuss, kit that I have seen.
Normally, I wouldn't like to argue with Chris, but this time he isn't correct in taking such a strong stand.
I tried ink jet refills couple of years ago and had a mess too.
Nevertheless, times change and a company is out there now providing excellent ink and refill techniques. I've been refilling now for some time and can get three to four refills a cartridge before having to buy a new cartridge.
Yes, they do fail after a few refills, as Shelly said. Right now I'm on my fourth refill, both color and black, with my new 5550 HP. You can get the "Universal" brand kit and photo quality printouts on glossy paper or regular paper.
I would encourage any of you that have had the same bad luck I did earlier to try these out.......
