i like this thread somebody asked how these openers last offroad well i can tell you very well indeed i have had one on my jeep for the last fifteen years its still there and very usefull in a dark field camping when you have not quite got smashed on westons cider and you need topping up you can at least still find your jeep and hence the opener....it saves fumbling in the tent or dropping it in the grass the opener that is i never drop my cider:)
