Easy to hook up and accepts up to 1/0 gauge. I used 2 of these to hook up my second battery, so when i need to replace my stock battery under my hood, i still have all my presets when I do. Great item to use if your wire is shorted out.

This device is very practical, good value, I use this for my amp set up, anytime I have to work on my amps I just switch off and I'm good to work on them, that way I don't disconnect my stereo and have to program it over and over every time I need to work on my amp set up.

This product was installed and worked fine twice. The third time I opened the circuit to do changes on my amp and it would not reset again. I don't even know if it would work correctly because it stopped working in a matter of three days and manually reset twice.
