I have the glasses of other manufacturers compared and returned again due to poor tone function. Either the base color is not transparent but already such a light tint sunglasses or was not strong enough. Here I was a bit surprised because the Tifosi offers everything. Clear in the dark and pleasantly dark smoke under direct sunlight. The change is within the scope and you should not expect miracles (tunnel entrance etc. is of course not brightened in the second pace).
All in all very recommendable, also due to its attractive price compared to its competitors (55, - I paid).
