Magnetic Key Holder, Magnetic Key Box Under Car with Signal Blocking Pounch for Faraday Bag&Tracker Zone, Waterproof Hide A Key, Magnet Key Case Hider for Car

Received this product quickly and at a very good price. I am now using it to store spare key on my RV. The magnet is really strong, it is very well made and has a wrap for key fobs to prevent detection. Simple to use. Big enough for most any auto key fob.

I’ve owned quite a few similar magnetic boxes meant to hold a spare key or GPS tracker but this is the the only one that doesn’t have the magnets exposed which not only gives it a sleek look but it also eliminates the risk of the magnets cracking. The holding force of the box is strong enough that I feel confident it will stay on the vehicle. Overall seems to be well crafted and a great value.

Very strong magnet! Seems to have a good seal, haven't submerged it to test the waterproof aspect but just by examining it I don't believe any water could reach inside of it in the normal scenario. I wasn't worried so much as it being water proof but more so the magnets, you have to give it a strong pull to remove it so I definitely recommend this if you've had some in the past with weak magnets. Seems durable, feels like very hard plastic, great price, it is quite large. About 3" wide x 4" length x 2.5" depth by guess. If you have a Samsung Ultra phone, add 2.5" of depth. That's about the size of this case. Not too big but not too small.

I was worried when I first received this product that the magnet would not be as strong, but it worked wonderfully! I had my husband install a magnet strip where I wanted to hide a house key and it worked perfectly. If you are considering buying, I would recommend.

I got this as a way to hide-a-key at home, not use on my vehicle. The magnet is so incredibly strong I think you'd have to hit some pretty good off-roading to knock it off your vehicle, unless you didn't get it fully secured. I put it on my fridge door to test it and have to slide it to the edge of the door to get it off, the magnet is so strong I can't just pull it off the door.A few people mentioned it is hard to open. I definitely can see that opinion, my first time opening it (because I don't read directions) was an interesting game, but figured it out. It has a nice strong latch, which since it's intended use is for under your vehicle I think is a really good thing.Since I'm using it at home I like that it is waterproof, we get some crazy storms, and I have a couple of really good spots that it blends in in plain site so no one will even notice it but I have a back up entry mode if I accidentally lock myself out, but also don't have to worry about it blowing away because the magnet is so strong.
