Review on 🔒 Locker BOXX - Secure Magnetic GPS Tracker Box - Waterproof Case for Under Vehicle Placement, Exceptional Water-Resistant Hide A Key Holder with Powerful Magnet (Compatible with Multiple Brands, Spytec GL300 Optimus) by Paul Hubbard

4 months of driving in the rain, snowstorms and just in case still under my car, great product, I don't know if it's dry, I use it only for the key. I base my reviews on actual usage. I would recommend this product. But make sure it's on a good metal surface with a solid connection and not a piece of metal but a piece of aluminum. Both magnets require metal for this to work properly.
