First it's a good reflector. Big, nice, with golden and green waves. As it's big it has strong spring inside = stronger spring holds better and ask more power to close. As well to close a cover - and That One Was not strong enough in my case. After fist time in the field cover lost a hang plus I have a small hole instead :) Who cares if reflector works right? ... That's how it losts one star to perfection marianmajik.com
