I have had one of the sensor mirrors for about two years when it stopped automatically lighting up. I use it every day, but I didn’t mind switching it on manually. Then the mirror came loose, & I contacted the company to discuss the best way to fix it. They responded with a very solid warranty process, which ended up with me receiving a replacement. I am absolutely delighted with this product and the excellent customer service I’ve received. Elegant design +high quality+thorough customer service = simple excellence
