Heavy-Duty Waterproof Magnetic Stash Case for GPS Trackers & Spare Keys - Rust-Proof Magnet - Color-Matched to Car Chassis

Very pleased. Very watertight and magnets are very strong. I spryed the box with car black paint so it mathes the underside of my car.

Excelente producto, muy buena calidad

Strong, and I mean strong, magnets. Nice build quality. Clasps nice and snappy. Environmental seal sturdy. Please measure your key before getting! I’m keeping the small one anyway because it is so darned nifty.

Great box! Super magnets!! I purchased three boxes (this and two MiniMags - The “2” and the Plus Extra Large) and tested for adhesion and water entry. All had 2 great magnets but the clear winner is this Gorilla Box. Then I placed all three boxes in a deep sauté pan and filled pan with water over the top of the boxes and left them for two days. The magnets held them under - all three were actually tough to get off the bottom of the pan. Opened the boxes and the Gorilla was completely dry. Check photo. The two MiniMag’s had a thimble each of water. This was not a scientific test but... I’m buying the Gorilla’s for my project. I have no idea how either brand will perform at 70mph in driving rain, but... again. Anyway, these were all nice boxes - sturdy as hell and the magnets on all three impressed. The Gorilla is roughly the same size and price as the MiniMag 2 - if you toss out the foam both should fit two sets of keys (2ea - key and separate fob). Certainly would fit a couple of key/fob combos and a large Tile (BT locator). If more space is needed you need the Plus Extra Large for $40ish. However there is nothing “jumbo” or “extra large” about it - it won’t fit a cell phone. A flip phone sure, but I’m a bit hard pressed to come up with a main stream application that the $20 guys can’t handle. Good luck.
