Both thread with which the rods are screwed into the feet were badly cut. A complete screw was only possible with the help of plenty of lubricant. With my Yamaha boxes (weight 0.9kg) the whole is an extremely shaky. The universal mount does not fit my boxing. Drilling soft so heavily on the pit holes that the installation is only possible with a rather than two screws. Thus, the entire construct is then so shaky that it is no longer suitable for my household. Too Bad. The price is good and for lighter boxes from other manufacturers designed a good solution.
