I’ve had mixed experience with them. A few worked fine for years. Some the key wouldn’t open the lock right out of the box, and one or two worked initially but the key quit working shortly. Good security, when they work.
When we moved from New Mexico to Kansas, we used self packing pods. Big containers. They'd pick them up when I filled them, I locked them with a discus padlock, then they'd truck them to Kansas. Worked fine. I have six of them now.
As an amateur locksmith, just side money hobby, ALL padlocks are easy pickings and a VERY LIMITED number of keys are necessary to open them!! They are safe from the HONEST!!
