Cracking Combination Key Lock Box: HUANLANG AMIR WJYMRO TEUEN ANKILO POMYDODU SISAV ORIA RESET-G14

The turn-knob key lock box is sold under one of the following "brand" names: HUANLANG, AMIR, WJYMRO, TEUEN, ANKILO, POMYDODU, SISAV, ORIA, RESET-G14. It seems that the known brand names stay away from this design. Current new price on Amazon ranges 25-30 dollars apiece.
These should not be considered secure because the opening combination is very easy to discover by anyone, and with a minimum effort.
