RE Epson WF-C5790

Hi, just wondering how people are using the chipless solution? Are you buying refillable cartridges or refilling the original cartridges?

If using refillable cartridges, are they like these:T9451XL
or if refilling the original how would you do that, just use syringe and block hole or go through cartridge nozzle/exit?  

Thanks
