Mark W from Two Rivers, WI said, "The product worked great but we were a little picky on where and how to mount the unit so it took quite some time. One thing it could use would be more air line or to leave the air line all in bulk and let you cut each piece to the length that you need. We also opted to mount the compressor unit under the hood. With living in WI the salt and winter conditions will stay clear of the unit this way.Overall great unit so far."
