The mirrors are relatively good, they were installed decently on the handles, I installed them but after one trip I took them off and put the regular ones back on. In my opinion, they are a bit dangerous, in traffic with many cars, they limit visibility to the rear because they are small, they also have a dark tint that requires quite a bit of effort to ensure what is happening behind. My opinion is that they are only suitable for low-traffic roads, not for heavy traffic.
