We needed a porta potty because of a plumbing issue that could take into the next week to be fixed. My daughter had hip replacement last week and I am old. I neglected to ask for a handicapped unit. After a day I asked if they had something to step on available. What a great guy. He said he was bringing us a handicapped unit . I said I thought we'd be okay,, but he said he was on his way. This company deserves 10 stars.
