Vortex replaced my Razor twice in just over a month. It just couldn’t take being frame mounted on a Trubor. They replaced it both times, but it now lives on the handguard of an AR.
I’m happy with the RTS2 other than needing a new battery every month or so.
Delta Point Pro sights (2 of them) have been perfect with no issues so far.
None of them will last forever, but Leupold gets my money for now.
