This box has the same serial number as its two predecessors. One gets from Metabo simply the current box - a lot of fun when ordering a previous version, because you will never know what ultimately matters. The last predecessor is functionally equivalent to the standard Tanos boxes that hot Systainer Festool. This box was just great and fully integrated in the Systainer-family. New Metabo has integrated a second handle in the box and the box should be compatible with the current Tanos boxes. For me, the bow did not go without power over the connector on the Metabo tool box. The metal bracket is wrinkled and looks cheap. The box does not fit aesthetically in the old. Was that of the T-seal feel the predecessor / is so far perfect. No idea why Metabo has verschlimmbessert here. I'll stay with Festool Roll board with Tanos, fine and Metabo Boxem in the same design. The correxes from Metabo can be backordered. If it is then time is no old Metabo boxing more, then you can resort to Tanos (costs a few euros more) or Festool Systainer (cost even less).
