CIS or Refillable or Pre-Filled? R280

I bought 2 sets of refillable carts and I can’t fill them up without spilling ink everywhere. So i’m looking at a pre-filled solution or a CIS for the Epson R280.

What do you recommend? Is a CIS harder then a refillable cart?

CIS is more technical than home-refilling at least at the set-up stage.
This varies with brand and model of printer.

Once set-up is complete, you simply maintain ink levels in the external tanks.
CIS is good for someone that is printing at high volume.
