The refill kit works great and saved me a lot of money. No complaints! It's the first refill on this cartridge so I'm sure I'll be back for another refill before buying a new one.

Worked perfectly straight away without any faults.  I'm a big shopper at Costco, but their ink refill did not work in my printer, it wasn't recognized, so I gave up and looked on amazon and tried this vendor Printronic.  I will use them again.

Works great. Easy to fill by drawing fluid through tube or pouring into top of injector with plunger removed.

Exactly as advertised.  Writes smooth and works great.  BTW a Standard Universal  refillable ink cartridge works fine.
