I have had one for 18 months or more. No problems, no water in. The only point to make is that the great internal visor which you can raise and lower as a shade needs to be kept clean, because  when you use it that could be four surfaces you look through to see the road.Other than that, fine. No visor will stay fully up at very high speed. It has a wonderful venting system, which can use the visor just open before finally clicking into place.I bought mine from the UK before they were available here and it cost me the same as the system 5 was then selling in NZ.However it was a bit OTT for touring in Thailand, so last year took an open faced job.
