The original mirrors on the GSA are not bad at all. I loved the change from round mirrors on my 2010 GSA to the skewed-squarish mirrors on my 2017 GSA. Until now I have not had any issues with them, however, I was made aware of the potential damage and cost crashing them could cause. After all they are an integral part of instrument cluster on each side of the handlebar, and an unfortunate mishap could not only damage the mirror but also the entire unit. That would without doubt cost some decent money.
There are many alternatives out there, with perhaps the Doubletake setup being amongst the more popular. However, I decided to upgrade to the Rottweiler Performance Quick Flip Arrow kit, together with the great Aussie-made Barkbusters and Storm hand guards. And guess what; I am super exited by the end result! See my upgrade and review on https://mygsadventure.com/2021/05/24/rottweiler-performance-quick-flip-arrow-mirrors-fitted-on-my-gsa-omg/
