Review on 🔒 Ultimate Protection for GPS Trackers & Spare Keys: Gorilla Box Heavy-Duty Waterproof Stash Case with Rust-Proof Magnet - Color-Matched to Car Chassis by Dink Rivas

The magnet is very strong, it cannot fall off the car while driving. You almost have to rip it off the fridge to get it off. I filled the sink with water and held it under water for 1 minute and not enough water came out to say. I bought another brand, a little smaller, and the chrome of the magnet corroded badly because I installed it on the front of the rear fender. I think it collected a lot of road salt and water. I'll put him in the back, which should help a lot.
