Hate the Price, but love the ink.
Style: Ink
I totally hate the price of printer ink, mostly when it dries out when not in constant use, but I purchased generic and my printer would not let me use it and i have avoided the firmware update. So back to buying epson ink. It worked the minute i loaded it into the printer. Epson ink is great. it was great color and quality. Just hate the price tag.

Pricey but they work
Style: Ink
Pricey but the remanufactured ones either don't work at all, or they work for a short time then go belly up...

Run out of ink quickly
Style: Ink
When you have the Epson work Workforce Pro 3820 it only accepts Epson cartridges none of the cheaper ones Epson cartridges run out of ink really fast I actually had some of the non-epson brand cartridges in there they worked a couple of times but then one day they absolutely refuse to work so they're worthless and then I had to actually buy the Epson brand name
