Customer Reviews

Here’s what some customers have to say about the Keystone – Indestructible Steel Crypto Cold Storage Seed Backup:

  • “I mean, what’s there to say? It’s letters printed on steel. Took probably a little under an hour to unscrew the plates, snap off and place all the letters, and rescrew. Had lots of letters left over once finished. It’s heavy and makes you feel like some sort of detective with a super secret password that only you can decipher (and, I mean, it IS a super secret password). Don’t plan to burn down my house to test its fireproof-ness, so I’m just going to trust.”

  • “Great product, cleverly designed, cheaper than most alternatives. The pin punch was trash and I used a real one with a ball-peen hammer.”

  • “This is a great product and very high quality. The only problem I have with it is the little screwdriver that comes with it is not a correct fit for the little screws… You should upgrade the screwdriver to a perfect fit for the little screws, apart from that this product is 100%.”

  • “Spreading the top metal piece reveals the real screws to remove. After which, placement of the letters (and them staying in place) was a horror. However, I used ‘rubber cement’ in the letter grooves, and I was able to successfully add all letters of my seed phrase. The little bit of adhesive kept the letters in place.”

  • “Nothing bad to say about this product. It is very easy to use and is quality material. Feels good to hold because it is a little heavy.”

Review 1

I got my Cobo Tablet yesterday. Very solid build (you could probably kill someone with it) and I had no problems with the screws. The screwdriver that comes with it works, but get yourself a set of magnetized screwdrivers as it makes the process so much easier. From start to finish, it took me about 45 minutes. A quick couple of suggestions for installing the letters. 1.) Keep the adhesive layer on the letters as you go. Some will get loose and you don’t want to lose them. 2.) Only remove the screws from one side at a time. 3.) Double, triple, quadruple check your words as you go along. The tiles can be hard to remove once they are in their slots. 4.) Watch which letters you use as blanks. Scan over your words and find the least used letters. Now, to all the one-star reviews saying there are only 4 letters per word and that the manufacturer does not indicate that: You probably should not be in cryptocurrency. You only need 4 letters to make the word, per the standard. That is the first 4 letters, not random abbreviations. As to the stripping of screws: Yes, the screws are small. However, most sets of screwdrivers come with the proper size for this. It’s a common jeweler’s screw size. Finally, I saw one review talking about removing the upper right screw that holds the entire set of plates together. You do not need to remove that. You just slide the one side out of the way, unscrew the side you are working on, close that side up, put all the screws back in and repeat.

This is a great product and very high quality. The only problem I have with it is the little screwdriver that comes with it is not a correct fit for the little screws. You have to push the screwdriver head hard into the screw to get it to grip properly. It worked out fine for me as I’m handy with things like that. But for anyone that’s not handy I could see this been difficult to do. But all in all I’m very pleased, as I said excellent quality and if you take a little care with the screws you’ll be fine. There is absolutely no need to pay $100 upwards for other wallets like this. This is as good of quality you can buy at a very very reasonable price. To the seller: you should upgrade the screwdriver to a perfect fit for the little screws, apart from that, this product is 100%. Thank you 👍🏽

This is a great product, just don’t use the cheap useless included screwdriver, get a bigger and better one and don’t tighten too much.

Review 4

I had zero issues adding my seed phrase to this item, which was incredibly quick and easy to do. Just unscrew a few screws, flip out the side you’re working on, pop the desired letters from the letter sheet, and add your phrase. It seems built well and I have no doubts that it’ll serve its purpose well and would survive fires, floods, etc. My only nitpick is that it differs from the photo and doesn’t look as clean as the design shown. Instead of the clean smooth design, there are several screw holes around the edges of the face/back of the device, with some of the screws being just a bit too long and protruding through. Not an issue for me really, but if you’re going to be storing this in a cloth bag or something where the protruding screws could snag on something, it could be quite annoying. Overall, it’s still a great value, and I’d buy it again since the main thing is build quality and survivability – which this seems to be built well for.

Review 5

Spreading the top metal piece reveals the real screws to remove. After which, placement of the letters (and them staying in place) was a horror. However, I used “rubber cement” in the letter grooves and I was able to successfully add all letters of my seed phrase. The little bit of adhesive kept the letters in place. Rubber cement did not cause a problem rotating the top metal pieces back above the letters.

Cons

While the Keystone Tablet offers many benefits, there are a few considerations to keep in mind:

  • Lock Compatibility: If you plan to use a lock with the Keystone Tablet, you may need to consider the size and design of the lock to ensure it fits securely. The interlocking plates at the bottom may require specific types of locks to prevent them from pivoting open.

  • Screw Stripping: The small screws used in the tablet may be prone to stripping, but most common screwdriver sets include the appropriate size for this purpose. However, this may require caution and care during installation to avoid any damage.
