Using this for deterring my hot rod being stolen. Good price for this. Installation was no surprises and just let them try to steal my hot rod now. First one that was ordered arrived damaged, went through the process of getting a replacement which was simple and received the replacement in a couple of days.

Failed after 2 months

Failed after about 2 months of being used as a battery isolator. When activated, only passes about 2 volts though the contacts on a 12 volt circuit now. Wasted my time and money.
