This thing is so cool. It reminds me of some kind of ancient alien artifact that was found inside a meteorite lol. But in all seriousness, this thing is built like a tank! Its over 1lb of solid stainless steel and precision machined perfectly. Just its mass alone guarantees that your seed will survive ANY house fire even IF the house burned hot enough to melt stainless (none do). Once your seed is punched in, its there forever no matter what happens. The disks are designed amazingly well and the deep etching is a huge upgrade from the previous model.
When you first recieve it, there is alot of play in the center rivot that holds all the disks together. When opened the disks will hang floppy. But this is by design... after you punch in your seed, the disks will deform slightly on the back (obviously). This adds thickness to each disk and that will remove any play in the rivot. Whether you have 12 words or 24, the loose rivet becomes tight when the disk is closed after punching.
I recommend NOT punching the disks while they are all stacked on top of eachother... this can leave a small dent on the disk directly below the disk you are punching. Instead, swing the disk you want to punch out to the side so its not resting on the disks below it. Place that disk flat on something like a bench, book, board, or something else hard that will support it.... then punch it. This prevents it from denting the other disks. Every center punch is different but I wanted nice deep dents so I punched each letter 4 times. Its personal preference.
Do this process SLOWLY! Follow every step in the instructions. MAKE SURE YOUR NOT MAKING ANY MISTAKES... this thing is too cool to mess up.
I am tempted to buy another one even though I dont need it lol. So cool and so durable. Remember, your SEED is most important thing. Storing it on paper is INSANELY irresponsible. Sure you can get a cheaper seed storage option but HODLR Disks are hands down the best cold storage option for your seed. The only thing I can think of that could make it better is to offer a titanium version. Honestly, that would be unnecessary... but id buy it lol.
5 big stars
The title says it all. Amazing quality in the packaging and the discs themselves.
I ordered the 3 pack and while it did take a while for the package to arrive, I wasn’t in a rush to get them anyway.
Definitely worth the wait.
Apart from occasional long shipping times its very good. Fair price.
Love the disks, high quality, heavy, seems very precise engineering 👏 love this!
