The product is generally good, is what I expected. Easy to assemble, universal ... but because there is a but, the arm is too short and the angle to position the mirror is too limited so it is not easy to adjust to actually see behind.
To really succeed in getting a good viewing angle, I had to force to successfully bend the collar fixing to get a better angle.
Installed in this way, it suits me well, so I do not regret this purchase.
