  1. JeepDad33

    Needed this bad boy for my OBA setup on my jeep. works perfect

  2. Andrew Breece

    Works perfectly and feels high quality

  3. jimmycorn

    Only last me a year or so before I have to replace it. They rust from the inside and then run the compressor until the battery is dead.

  4. Bruce Rubin

    lasted approx. 6 months before it closed up at the inlet nozzle and stopped working!

  5. Michelle Powell

    my wrench slipped and broke the plastic housing. I was able to glue it back together.

  6. G. Moore

    Works as designed. Heavy electrical load design.
