We had maybe 20 minutes of time to go over the portable unit and it didn't even work when we needed it! We had Randy and two of his salesman over to help sell their services. Randall over promised and his son Chris spit in our front yard and wouldn't be quiet... a true car salesman! The only person we did appreciate was Matt which quit Randall's company soon after probably seeing what a mess of a company they were running. Do not do business with Randall Rhodes!
