Review on 🪟 2 x 3 Inch Small Survival Signal Mirror - Military Grade Emergency Signaling Mirror with Compass & Whistle for Camping, Hiking, PFD Rescue by David Garnic

Visit the Dollar Store and shop for a makeup mirror, compass and whistle. You get more features than that. I can't signal anything accurately from a distance, I can't speak out loud. Aiming at it is pointless. I can't see a 10 foot square box 100 yards from the sun. I don't even see the same box from 30 feet away when looking at the sun (like using it as a signal mirror). Imagine trying to give a signal to an airplane or vehicle.
