The mirror is good but 3 months after using it, I would not recommend it. Its positives are that it is discreet and when properly positioned, you can quickly see if a vehicle is behind you (especially at night). Its negatives are that it easily loses its position, so you constantly have to readjust it. Another negative is that it is so small that you cannot distinguish details. Additionally, the manufacturer's logo (Author) on the mirror further reduces its surface area. In terms of construction, it is good for its price. It is made of plastic and is not fragile. There was one instance where it fell, and the only thing that happened was the mirror separating from the rest, but with a little pressure, it snapped back into place.

Excellent little mirror. Small and discreet but enough to see everything behind you. It has a parabolic shape and a wide angle, so it has no blind spots. You can see the car even when it has reached your side and is overtaking you.... It never loses its adjustment, even on multiple bumps.... It fits securely with a plug inside the steering column and is supported by a ball.... When you leave, you can easily remove it with one motion and put it in your pocket as it is very lightweight....
It is the best thing you can do for your safety after wearing a helmet....
