  The use of Landau cavities was foreseen for both the 1.5 GeV and 3 GeV storage rings at the MAX IV facility from conception. Along with increasing the Touschek lifetime and reducing the emittance degradation due to intrabeam scattering, their purpose is to stabilise the beam in the longitudinal plane. They now play a crucial role in the everyday operation of the two storage rings. This paper outlines the current status and the aspects of longitudinal beam stability that are affected, positively or negatively, by the presence of Landau cavities. Their effectiveness in the two storage rings is also compared.
