Attached on a Benelli imperiale (max speed of 120 km/h). Worth the money. Depending on your handlebar it may need some extra work to attach them properly (different screws etc). Other than that they look great, have good visibility and zero trembling

Sturdy construction. They don't move even at speeds of 130+. A very honest choice for their price.

They are decent mirrors for city use. Unfortunately, if you want to accelerate a bit, they can't handle it. On the second day of having them, while on the highway, one of them started shaking so much that it became loose and was about to fall off. These screws are inverted and inside the mirror, so you don't have access to tighten them since the mirror is glued.

I criticized them only for their appearance, but in the end, they work perfectly fine! I didn't expect it..

Very honest for their price, they were installed as clip ons.
Good visibility for their size, no problem with vibrations and they slightly increase the width of the motorcycle.
Very attractive to the eye.
Due to difficulty, I placed the rubber that the handlebar had internally as a counterweight and then the "spacer" it has, making them even more stable

I had tried other Chinese-made products as well, at the same price. These ones are superior both in terms of vibrations, which I had an issue with the others, and in terms of visual field since they have a curved mirror and you can see everything.

No comparison to others I've had. It shows sturdy construction and has a good field of vision. The only downside is that it increases the width of the handlebar, like almost all mirrors of this type and price.
