George, the owner, is friendly and likes to be helpful. I will not say he is dishonest, but after questioning him about four times concerning re calibration of the safety camera on the windshield, and having him indicate that he could take care of it, he did not follow through. He installed the windhield the next day after calling him, and did a good job with that. I had to go to Don's Mobile Glass for recalibration where they said the camera was just dangling in the holder and the cover had been broken and superglued back together. I paid for a new cover and had to be reimbursed by insurance for the re-calibration. If you have the safety features in the windshield I would not recommend Certified. If it is just glass make sure you have all the details worked out. read more
