The vibrating "rumble" capability has been replaced with a far more practical "doggy poop bag" function. Though this leash is completely functional paracord may not be suitable as a leash for larger dogs.

I used a broken XBOX controller for my dog leash. There were 7 screws on the underside holding the controller together, with one hiding under sticker.
When all screws are removed the controller can be easily pried apart.
