error-free
Completely without flaws
Error-free means without mistakes or flaws.
The term appears most often in technical contexts—computing, manufacturing, data transmission—where precision matters: The system completed three error-free test runs.
Outside technical use, error-free describes any performance or product without defects: an error-free essay, an error-free game from the shortstop.
