"Perfect and smooth journey, Jorge came pre instillation to check the electrical panel and where the the charger was going to be installed and after the review he text me the cost of parts and installation, after I received the charger he came on time and the job was completed. I was updated by text messages throughout the process. In the future if I need any electrical work I definitely use JK Flores Enterprise."
