My workshop at home comes in handy! I suspect mine are quite high force. Car gets less use than it used to but opened when it's washed. Don't have to check before every journey like a British Leyland!It's nice when you have tools and place to work
Mine have no problems, couple of years since installed. Maybe it depends on how much one drives/opens the bonnet.
Always remember a VW dealer telling me once they can see how many times the bonnet has been open between services.
