I'm a big proponent of the product and the people behind it.
When I decided to upgrade my IBA site with Petit machines, I started researching tellers. The two at the top where qualify and sunny as there weren't any cars out in the wild besides at the founders sites. I learned about them on social media and decided to look into them some more, and really liked the technology that they used and the end users appearance and usability.
Going with a dual Petit set up with the Dencar running monthly plans has absolutely transformed my site for the better. I'm washing way more than 2x ( including single wash purchases) the vehicles per year than I did before. Even my SS side increased significantly due to the site being overalll busier.
