They are good quality cables!!

does exactly what it says, sturdy cable + lock, love it

I was super confused about the locking feature, but its just a friction lock on the earth pin - it doesn’t affect the fit or function of the connector. If you’ve ever had a loose power cable during a gig, this is a game changer. To release, there’s a red pin on the IEC connector you push to release the grip

Great Cables with the lock in ability, definitely useful!

Great cable with locking function
