Defuse the Cables Escape Room Prop

Brief introduction:
Similar to the Defuse the Password prop, this one requires adventurers to defuse the 4 cables attach to the bomb-like box to open a lock, door, safe, lights, etc.

There are two models to choose from. Please indicate which model you would prefer, or we will send one at random:
Model A: Defuse one of the four cables to trigger the prop. 
Model B: Defuse all four cables to trigger the prop.

Prop list:
1 4-cable box
1 controller
