The visor works as advertised. It's a good alternative for an internal drop down tinted shield. I do notice a slight pressure when visor is up, and I turn my head, but it's not a deal breaker. The vent doors/covers are a seemingly cheap afterthought, and add wind noise. Conclusion...Fit, finish, and function are excellent. Minor complaints...cheap vent doors, increased wind noise, and in certain conditions, a bit of extra vibration.
First you felt it's a rip for a visor in this cost. But eventually you realized that it's really worthy. Instead of wearing sunglasses, you no longer need to change glasses if you have nearsight. This is a good value-add item.
I'll higly recommend it.
