How we work

Independent. Cohort-normalized. Updated every six hours.

We don't have an editor's pick. We don't take fees from manufacturers. Every kit is broken into the same seven roles, scored by the same formula, and re-priced from live retailer feeds.

No editor's pick

Rankings are formulas, not opinions. Same math for every kit.

Editorial policy

Real build cost

We add back the parts kits leave out, and price them at retail.
