Excellent kit
Everything came expertly packaged in one box. Easy instructions and easy install. Isolator works as described and I can now listen to music and have all my lights on without worrying about draining the starting battery.

Awesome kit
The media could not be loaded. install was super easy if you have the right tools. a right angle adapter on a 1/4 impact came in very handy. only took me about an hour to install on my own. now i can play tunes while parked on the trails care free!

Bad battery
My dad bought this same kit for his RZR and it was great. I bought it in September 2022 and the battery was bad by December 2022 even though I keep it on a battery tender. These batteries aren't the best.

For battery power
Put it on 2018 Polaris razor for extra battery power for all my accessories, so main battery is only for starting razor but they charge together.
