Not true EcoTank-style compatibility with ET-15000 refill ports
Color: B/B/B/B, Color: B/B/B/B
I previously purchased the full Hiipoo sublimation ink set for my Epson ET-15000 and had a great experience. Those bottles included the correct EcoTank-style keyed refill tips that insert directly into the printer’s tank ports and allow clean, gravity-fed filling.
Because the black tank gets used faster, I later ordered the black refill bottle separately. Unfortunately, this bottle does not include the keyed EcoTank nozzle. Instead, it comes with a pointed tip and syringes for manual transfer.
The syringes also do not fit the ET-15000 refill opening, which is designed for the keyed gravity-fill system. As a result, I had to attempt a manual pour and ended up with ink spilling around the tank area.
The ink itself has worked well for me in the past and I like the Hiipoo brand overall, but this refill bottle is not directly compatible with the ET-15000 the same way the original set was. Buyers expecting the same refill experience should be aware of this difference.
