Hope vision one is fine for me, been using it for 3 months on my bars, no other light, lasts for over three hrs on full, done 3.5 hr night rides over rivvy and belmont etc.
The mount has not come loose or wobbled, been down everthing with it on, the eliminator, tearooms and san marino etc and you would have to be bloddy quick to get past me. Works perfect and enough light for riding v fast off road with no other light IMO.
