I have an old 6 Collar Trash Breaker Shocking System. I believe two of the collars still work. I have no idea what it costs to refurbish these systems, but I don't need it anymore. I'll sell this whole system for $100 if anyone would like to see what they can do with it. Chargers are included. You can call or text me at 850-272-1983, send me a check/money order and I'll pack it up and send it your way. Shipping is on me.
