Here's my story. So I ran out of ink in my HP825c printer. Went out and bought a couple of those black ink refill bottles with nozzle. When I tried filling my ink cartridge I learned the inside ink was contained by a plastic bag. So when I punctured that bag ink went everwhere. Guess it's one of those that doesn't accept refills. Short of paying $35 for a HP cartridge on a $15 printer. Do any of you use the refill inks and if so what model printer/cartridge accepts these refills. I'd rather buy a printer that uses refills. Thanks
