Reviews and User Testimonials
It is a steel device that you can use to mark down your recovery phrase and then subsequently seal it up to keep it protected. It is water-resistant, fire-proof, shock-proof, and stainless. This makes it practically indestructible (…)
The capsule looks absolutely robust and resistant (…) The deep thread hermetically seals the capsule and thus keeps the information safe even under water. The capsule can withstand the impact of a 9 mm projectile.
In summary, for bitcoiners, and also for anyone wanting to protect passwords and other information, it is a good way of moving to a robust and compact offline storage for seed words, and could be used in a variety of security configurations.

The Cryptosteel feels sturdy and I can definitely see how this product can survive all kinds of natural elements like fire, pressure, corrosion and acid. ... I would recommend the Cryptosteel if you have a large cryptocurrency holding as it offers more security compared to writing down your mnemonic sentence on a piece of paper.

The Capsule’s cylindrical design makes it a pretty inconspicuous product.
Zaista je teško zamisliti kakva bi to kataklizma bila u stanju uništiti kapsulu do te mjere da podaci pohranjeni u njoj postanu neupotrebljivi.
Such a great piece of Engineering! @cryptosteel made a product that’s accomplishing its goal, but it’s also sexy.

This product is awesome! It doesn’t require any outside power. It can withstand the elements . You can zap it with a million volts and it will survive.

This is amazing. Moreover, I like the idea of an open source hardware project.

Best way to stash your passwords or private keys. Love the packaging, too.

We have been Cryptosteel users for the better part of 2017 and have nothing but the best things to say about it. We literally tell everyone in our network, be it our investors, partners, or clients, that if they are looking to securely store their seed passphrases or other critical data, they need to look no further than a Cryptosteel as it really is the best solution.

Cryptosteel is THE most secure way to back up a cryptographic private key or seed. Cryptosteels give you CCSS Level 3 compliance right out of the box, being impervious to fire, flood, static electricity and even EMPs. I truly believe there is no better alternative.
– Michael Perklin, cryptocurrency security expert and CISO at ShapeShift.
The product got me thinking about my digital inheritance plan I’ve been working on recently, and it seems like a superior backup to paper. In fact, CDs, paper, USB flash drives, hardware wallets, and other products could easily be damaged by fire or break down over time. Cryptosteel can definitely survive these types of elements but would also have to be hidden in a secure location. … Overall the product is an interesting way of storing Bitcoin private keys, PIN numbers, and lengthy passwords in a near-indestructible fashion.
