Great part
Easy install. Just gotta adjust the two screws on top of the switch so the air compressor shuts off at your desired PSI. Works great!

Did not work, like it was supposed too.
Everything went Great, but on installing the switch, it would not shut down the compressor. I let it run for 15 minutes on the high end of the compressor and it would never shut it off. I have sent it back for reimbursement, and will order a new one at that time. They are preset and know that you just sale them.
Will write a review when a get a new one from you.
