It tripods BS 150 is good enough but for me it is not worthy to be called Bosch Professional. The quality of molded plastic parts is improved, my upper tray is not perfectly puts horizontally while the feet are level, it is necessary that I play on the latter setting.
Bearing the model BT 150 I strongly suggest it is far more successful. The section of the structure is greater. He climbs a little higher (157 against 147 cm) and is a bit heavier. Molding plastic is better.
