Even bigger sockets are securely held, in other words it is hard, so personally, it was better to push the knob to pull it out. (SK - 11 one - touch socket holder) However, there are some people that one cushion of "push the knob" is troublesome. Maybe you like it.
Since 12.7 sq of socket has increased, it purchased. I was using other brands of cheap items, but the moderation of fit is not good, so purchase this KTC's one. With a sense of moderation as expected, it is convinced with the KTC brand as expected. If the socket increases further, I will purchase additional.
