Aluminum Alloy Waterproof & Shockproof Case for Ledger Nano X/S Plus, YubiKey 5/5C NFC Case, USB Thumb Drives – Secure Portable Storage for Cryptocurrency Cold Wallet(Silver)

I recently bought the “BIU-BOOM Aluminum Alloy Waterproof & Shockproof Case” and I’m quite impressed with its build quality. The carabiners are super strong and the twist-locking mechanism requires several twists to lock and unlock, so there’s no chance of it slipping off. The metal container (I think it’s aluminum, but I know it’s metal, not plastic) has threading that requires three full turns to remove, so it shouldn’t fall off either. There’s also an “o-ring” that should make it at least very water-resistant.Now, I’m not going to bash this product for its build quality because it seems a bit overkill for storing a 2FA key. I believe four Yubikey 5c NFC keys can fit into one of the cases. The product is listed to hold “USB Thumb Drives,” which I did put the SanDisk Extreme Pro into the case (just one drive) and secured the lid.I bought this case to protect the contacts on my Yubikey 5c NFC 2FA key, but I think it’s a bad choice for what I intended. So, I’m writing this review to warn people who have the same idea as I did that this case is far too big for most to have on a keychain.In the listing, they mentioned “Ledger Nano X/S Plus, YubiKey 5/5C NFC Case.” I don’t know the size of the Ledger Nano, but the picture shows the Yubikey, so you can get a sense of the size. I also included a size comparison with a common vehicle “key fob” for extra comparison (no the fob does NOT fit inside).The included lanyard is okay, not great, and the carabiner is much more secure for “belt loops,” etc. I believe this is a very good product, but it just is too big for what I hoped to use it for initially.I hope this helps people with a size comparison, as it seems to be a very well-made product.I'm giving it five stars because the product is very good, just too big for what I intended to use it for.

The construction of this case is solid, and it includes spare o-rings and pre-cut foam inserts. It is larger than expected, accommodating two average-sized thumb drives or Ledger Nanos. It’s versatile, suitable for storing electronic devices, medication, money, keys, or anything that requires protection from the elements. However, it’s important to note that this case is not completely waterproof and can rust easily. To mitigate this, consider adding an additional layer of rust protection or using it as a secondary layer of defense. Remember to employ a defense-in-layers approach. For instance, place a sensitive thumb drive inside the capsule, and then store the capsule within a fireproof bag, securely placed in a locked room or vault. While it fulfills its purpose, it’s not a life-proof capsule, so it’s essential to keep that in mind to avoid disappointment. It’s unclear whether it works as a Faraday capsule, so if anyone tests it for that purpose, please share your findings.
