  Recent controversy regarding the meaning and usefulness of weak values is
reviewed. It is argued that in spite of recent statistical arguments by Ferrie
and Combes, experiments with anomalous weak values provide a useful
amplification techniques for precision measurements of small effects in many
realistic situations. The statistical nature of weak vales was questioned.
Although measuring weak value requires an ensemble, it is argued that the weak
value, similarly to an eigenvalue, is a property of a single pre- and
post-selected quantum system.
