    Locking feature is great

    Love the locking feature that keeps sockets from falling out. I’ve had sockets fall out for example when removing/installing spark plugs and this keeps that from happening.

    Great combination with Zyklop ratchet and Wera sockets. Haven't had any issues with my old Craftsman sockets either. The locking mechanism works good.

    The locking mechanism works great, and the black collar is quite nice for holding the extension while loosening or tightening bolts. Fit and finish is top notch. Highly recommended.

    Nice quality. Lock is push through shaft, works fine but some might perfer a slide button type lock.
