Hi All,
I have an S4 been using it for about 4 months now, I have the grey one with graphics.
+
Gold rated.
Very light.
Excelent vision.
Visor hasn't scratched even tough I miss treat it.
Comfortable (mines a M, have a slim 58 head).
Easy to fit intercom (fits ok dont know its there, but mine was an ebay special using PMRs).
Strap release catch.

Peak can catch a little in the wind at speed but its easy compensate as long as you remember its there

.
Noisey face on to wind, whistles, but turn a few degrees to the side and its quite.
Cheep, everybody will have one.
Looks a bit odd without the peak.
