Purchased this to adjust the beam pattern as it was off. 7mm hex head fitted the socket and worked as advertised. I can't comment on the torque level but it was adequate for the task. As for comfort it's a metal tool, wear gloves if required, easy to control depending on your CNS I suppose. Enjoy
Btw, 7mm is the one hex socket not supplied in kits, that's why this review now exists.
