Same summary

This 4-in-1 set with a 21V brushless motor combines an impact driver, drill, sander and impact wrench in one practical package. With over 200 Nm of torque, two included batteries and a case, it makes the most sense for home users who want to solve a variety of tasks - from assembling furniture to occasional more demanding tasks where more torque is needed. The set is suitable for renovation work, renovations and situations where a quick change between functions without additional tools is useful. Due to the higher weight and complexity of the tool, it is less suitable for very precise or long-term overhead tasks; however, for regular professional use, it is worth considering that a universal set is a compromise of flexibility, not specialization.
