Halfords Professional Snap Fit
Price: £19.99 No. of tools: Nine (1.5-10mm)
A clever twist on the ball-end theme, and all but the three smallest pieces have snap-fit locking rings built into their ends. These provide additional stability when the tools are used at an angle, as the bolt stays connected to the key, making positioning and removal foolproof. But poor size markings on the pieces and the clasp lose this set points.
