Uniwork Compatible Refill Ink Bottle Replacement for Epson 774 664 T774 T664 for ET-2650 ET-2550 ET-16500 ET-4500 ET-4550 ET-3600 ET-2600 ET-4550 Printer Tray (Black, Cyan, Magenta, Yellow, 5 Pack)

Not a good product. It killed my printer.

These bottles are unusable with my Epson printer, despite the description. Epson printers require a compatible nozzle for refill. A total waste of money.

The bottle has a two part cap, the first screws onto the bottle and the top tapered portion screws onto the cap base. These were delivered with cracked caps and as a result they leak. The basic design is good but defiantly is flawed. I bought these earlier this year and have just now had to use them. If you buy this productt, make sure you inspect them carefully as soon as you receive them. I have spent the last several hours trying to remove the leaked ink from my floor and carpet. Very disappointing.

Ruined my printer. Cant clean the print heads. Do not buy.

No instructions No contact info for “Reliable Customer Service” noted on the box for “our team to assist you” You might be able to fill Epson bottles but not the eco tank. I should have just ordered from Epson and have gotten the Keyed filler tip spout on the bottle

Not compatible with ET-2750 as stated Update 10-11-21 Vendor issued a credit for this purchase

Appear to be as good as OEM. I've used aftermarket inks my entire work life and have never had trouble with them. Mostly Epson compatible, and some HP compatible too. This ink is no different. These fill my EcoTank Printer with ease. Well worth the money.

This is mostly in reply to the reviewer that wanted to know why his Epson 2550 printer didn't reset the ink levels automatically. If you RTFM, you learn that there is no sensor that detects the ink levels. You must go into the maintenance menu for ink levels and select which tanks you refilled. The printer just keeps a count of how many pages it has printed, and estimates the ink levels by the page count since you last reset them. It is just a timer of sorts. I can't believe someone returned their ink over this issue. As far as the ink goes, it works just fine. Each black ink bottle is good for about two tank refills. The color bottles are a little smaller, but still more than a tank's worth. The bottles are more-or-less permanently sealed, so you should cut the foil with a knife as recommended on the bottle. The built-in spout is long and narrow, so a no mess operation is possible (wear gloves and have a paper towel ready if you aren't careful). If you tilt the spout toward the back of the tank you can easily see the ink level rise as you fill. These large reservoir Epson printers are great! No more hunting for expensive ink cartridges, no expensive ink subscriptions, just pour in the cheap ink and I have to refill less than once a year. I love it!
