Review on PAC PAC-500: Power-Packed 500-Amp Relay Battery Isolator for Superior Performance by Sean Zamora

A bit pricey not sure if they are exactly the same as others for a slightly lower price but they look the same in the pictures at Revain. Without editing and testing all versions, I can't say. After seeing this model of PAC everywhere I realized I spent extra shekels as I have to rely on it. Arrived well packaged, in perfect condition. The mount is very secure. I have a heavy hand but based on another reviewer saying he broke it while tightening the connector nut I was careful and had no problems. I was able to tighten all of the connections with great satisfaction with no issues or cracks. I hear a click in the jeep, I can tell when it's closing or opening. So far as good as turning off my Zeon winch.
