You have a good product
You have a good product, although pricey, it will stop the damage birds nesting under our solar panels are doing to the roof. Your installation video needs editing. It suggest securing the clips by bending the shaft after sliding the lock washer into place. This simply loosens the clip. It does not lock it into place. When I called your technical support person, he was surprised by that advice. I always just clip off the excess he told me, which was exactly the work around we were using.
