It is argued that, with few exceptions, WR stars in binaries are essentially indistinguishable from single WR stars of the same subtype. In particular, mass transfer from one star to the other can be neglected, being completely dominated by the winds and their interaction. Empirical masses and mass-loss rates derived for WR stars in binaries are then examined as typifying WR stars in general; they are used to derive a plausible scenario for the evolution of WR stars.
