The honest comparison
Compatible vs OEM: what you're really trading
No star ratings, no "our favorite." Just the trade — what OEM buys you, what it doesn't, and the price gap on parts we match to your model.
OEM buys you
- Guaranteed fit and media, straight from the maker
- A warranty relationship if a defect is ever the part's fault
- Zero research — the box already says your model
OEM does not buy you
- Better filtering when a compatible part fits and seals correctly
- Protection from a wrong-model purchase — that's on the match, not the brand
- A fair price — OEM consumables run 1.5–2× the compatible part

OEM figures are typical street prices, not our sale price; PartFit prices are representative market snapshots for the compatible part (see any product page for the basis). The number that matters isn't the discount — it's that the part fits. Match your model →
Our rule
We compare on verifiable facts — fit, media class, price — never on a subjective score. If we ever can't verify a compatible part fits your exact model, we don't call it a match and we don't sell it as one.
