I find the Walimex Pro WT-501 Boom Stand well and it would buy again. Amazon sends this 7KG heavy boom stand in a plastic bag wrapped in a large box. The problem is of course that the 7KG can move heavy part during transport free, are then free the forces have led to the case of two deliveries the tripod destroyed us arrived. Of course, Amazon replaced the damaged parcel without any problems.
The walimex pro WT-501 Boom Stand in itself I think is very practical and is of good use
