Nothing comes close to this set from Challenge in terms of value for money. In total, there are 80 pieces, catering for virtually every screw head style imaginable, and nine sockets spanning five to 13mm. The driver itself is not as torquey as some here, but it’s punchy enough and lasts for a decent amount of time between charges. We also like the soft rubber material the tool is covered in, the movable hinge and the very intense built-in LED light. A worthy Best Buy.
