I had one a few years ago and it was ok for short trips in the summer, bought a new one after that and it's bloody awfull, lining from chin piece has fallen out, it leeks in the rain, and the popper studs don't line up properly.
Got a schubeth now and well happy, if its hot i take the clear visor off and use the flip down tinted, and the visors got a setting that pops forward a little bit to stop it steaming up at low speeds. Would'nt touch another Roof after this.
