The torque control device is a must for Bosch IXO. This accessory would default at each IXO be there! I use this when IXO IV and am very satisfied. Now you can respect even without full concentration. The timing screws attach the same without the work to destroy. The quality, processing and handling is very good. A star deduction I give the torque control device, since the weight distribution to the top unfortunately shifts forward. The essay is needed as a tool, robust and therefore the weight noticeably. This would now minimally tip forward the IXO. However, this is low and interferes little!
