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.

Works great

I used this to turn on with key on power in my truck. Power then goes through this and turns on my key on fuse panel. That way I can run a much larger cable from the battery to the fuse panel instead of pulling power through the ignition switch, where power output is limited. So far it doesn't get hot, though I am not running anything close to 500 amps through it. More like 75 amps max and even then it's only sometimes. No problems so far.
