I noticed 9 votes, but as multiple votes are allowed and the percentages total 112.5% or 9/8, I think that 8 persons voted. Then 6 are only refilling OEM, one is only using refillable compatible cartridges and one is using both refilled OEM and refillable cartridges.
It looks to me like only Canon owners voted, I think most use the older models for which resetters are available and a few are forced to use refillable cartridges as no resetters are available for the newest Canon cartridges.
This is only guessing and very uncertain, so please more votes and more posts with comments/info.
