I have used mine on dirt bikes (dual sport) for years and find they fill the bill. I can use then when necessary to look back and then fold it down out of the way. True I have to fiddle with it but it's for a dirt bike. It's made of plastic and resist breakage (I have never broken one in more than 20 years of use. I wouldn't have it on a street bike or a 90/10 street/dirt Adventure Bike.
