Magnetic Key box, Hide A Key Magnetic Car Key Holder Key Hider, Waterproof Hidden Key Holder Car Key Case for Outdoor Travel, Magnetic Key Box for Under Car Vehicles (1, Black)

Magnets are powerful and hold well. Inside is big enough for a fob and it's padded inside. Would hold on a car wheelwell and not fall off.

The box is thick composite material. The magnets are strong and secure. The item is better quality than I expected.

Incredibly strong magnets! I really liked it, would but it again.

This is a great size little key box. It seals airtight waterproof. Very well made. Foam inserts are nice inside so keys aren't rattling around. The magnets are super strong. This has already saved me once when I couldn't find my keys and I was in a rush. I bought a second one for my other car. Would buy again.

Much better than those old slide "key holder" type of spare key holders. This will hold a large key fob and keep it secure and dry, no matter what the weather or road conditions. However, even though this is water resistant, it isn't waterPROOF and won't keep the contents dry if submerged in water.
