Rich at JBL is a true professional; he’s my go-to guy now. He is smart, analytical, determined to solve the problem and stands by his work (returned three times to make completely sure the job was done right!). Also against his financial interest, gave us tips and products to prevent the clogging problem from returning again. This is a young guy with an old-school work ethic & he deserves much success for his dedication. Simply top-notch!
