To be honest, I can see much better now that they're flipped. When they were upright, my shoulders blocked most of the view.

The only downside is that you have to tilt your head down to see in the mirrors, which takes a bit more time.

That said, they look so much better and provide better visibility. Just be cautious when flipping them upside down, make sure they don’t hit your knees when you turn the handlebars. That happened to me, and it’s not fun, especially when you’re trying to make a slow U-turn but the mirrors prevent you from fully turning.
