Hi,
I've fitted them to my Landcruiser and they are fine. You can get good air flow, window part down, even when raining quite heavily and they cut down on wind noise when windows are open. Being tinted they also cut down glare and low sun but I do sometimes bang my head on mine when sticking my head out to reverse.
Yes, very easy to fit, did mine in the car park of the motor factors where i bought them.
