The set is not suitable for professional use but is intended solely for use in the home. Although it does not come cheap, I would not recommend basing your expectations on its longevity on continued use. Has pros: A portable case, a comprehensive collection of additional components, a magnetic holder, and a universal handle are included. When shook or even dropped, the rig will not come loose from its mounts because it is securely attached to them. Below are some downsides: Absence of a 12" head, which is one of the most widely used but low-quality drills. Due to the secure nature of the attachment, it is impossible to remove the equipment using just one hand.
