I bought an original Metagal rear view mirror at a store in Sorocaba, SP. I had already bought another one, on the right side, which I was satisfied with. However, this new rear view, on the left side "shakes" the image. The shopkeeper made the exchange, but the new Tbm trembles, which bothers a lot. I would like to know what may be causing this defect and I sent several e-mails to them, who return to my mailbox and by phone Also I was unable to contact. They could put a valid email on the site, so we can get in touch and ask questions.
