1. A set of panels comprising a first panel, a second panel and a mechanical locking device for locking the first panel to the second panel, the mechanical locking device being configured for an assembly by a displacement of the second panel in relation to the first panel in a vertical direction to obtain a locked position of the first panel and the second panel, wherein the first panel comprises a first edge, a first panel surface and a second panel surface, and the second panel comprises a second edge,
wherein the mechanical locking device comprises a locking strip extending from the first edge in a direction parallel to the first and second panel surfaces,
wherein the locking strip comprises a locking strip edge,
wherein the locking strip comprises a first locking strip surface extending in a direction substantially corresponding to the direction of the first panel surface of the first panel,
wherein the locking strip comprises a second locking strip surface extending in a direction substantially corresponding to a direction of the second panel surface of the first panel,
wherein the locking strip comprises a locking element configured to cooperate with a locking groove at the second edge of the second panel for locking in a direction parallel to the first panel surface,
wherein one of the first or second edge comprises a tongue configured to cooperate with a tongue groove at the other one of the first or second edge for locking in a vertical direction,
wherein the mechanical locking device comprises a first flexing groove extending from a transition between the first locking strip surface and the first edge and into the first panel at a third angle from the first panel surface, and the locking strip is configured to flex by varying a shape of the first flexing groove during the assembly, and
wherein the first edge comprises a first positioning element and a second edge comprises a second positioning element, the first and second positioning elements being configured to engage with each other and decrease vertical movement of the second panel relative to the first panel toward the second panel surface in the locked position,
wherein the first and second positioning elements each have a set of corresponding engaging surfaces, and wherein a first angle between the engaging surfaces of the first positioning element, and a second angle between the engaging surfaces of the second positioning element, are both about 90°,
wherein the first positioning element is located on a portion of the first edge, wherein the first positioning element is located between the first panel surface and either the tongue or the tongue groove,
wherein the second positioning element is located on a corresponding portion of the second edge.
