Cons

•Battery installation and removal are tricky and can risk breaking parts if screws aren’t carefully loosened
•Not designed for heavuty tasks like lug nuts or lag bolts
•Some users find the size could be smaller for even better handling and comfort
•More expensive than some alternatives like impact wrenches

Bottom Line

The MILWAUKEE 2402-20 M12 FUEL Hex Screwdriver shines as a precise, powerful, and ergonomic tool for fine, detail-oriented jobs, especially automotive and electrical work. Just don’t expect it to replace heavier-duty tools or handle larger fasteners like lug nuts. If you're looking for a reliable, comfortable driver to use all day for delicate tasks, this is a great pick. However, if you need a more multipurpose or heavy-lifting tool, consider complementing this with a cordless impact wrench or drill for broader use.
