So first, you only need to enter four letters, some will ding the product for this, but they're really dinging themselves a 4-star review on life and intelligence. :-) I can validate that even on a hardware wallet (Ledger) the recovery phrase works fine, once you enter 3 letters it gives you a host of answers that have those 3 letters in common (and yours is in there, and when you apply the 4th letter only ONE of the selected options qualifies for the right answer).I added all my phrases, ran the ledger recovery app and tested all 24 words and scored 100% on the validation.Minor issue with mine, one of the screws just wouldn't come out of the plate... it must have been machined a bit wrong in the thread, I pretty much destroyed / stripped it trying to get it out; ended up having to pull the metal apart a bit to get that last one to pop out properly or hit it from the reverse side to 'break' it out of the hole. I tossed that one in the garbage and used one of the additional replacement screws that come in a small baggy since it was pretty stripped and destroyed.The process is tedious, no doubt, adding letter by letter for 24 words; but it worked, can't ask more than that (although I didn't burn down my house to see if it survived my fire resistant safe)

After setting my seed phrase and screwing down all set screws securely is was very loose. This caused the seed phrase letters to come loose and fall out of place. That's a disaster if this is your only way of storing seed phrase! Luckily I caught it and ended up putting a small bead of super glue to keep the letter plates from sliding around. Get the imKey HeirBox instead. The letters are very secure in the imKey.

Product arrived quickly and had all the features that were advertised. Packaging design needs help though- the screwdriver was loose and free to bang around and scratch up the front of the product; the foam insert in the packaging doesn't prevent this because it is too small both in height and in cross-section area...it's just glued to the inside lid of the box and doesn't touch or protect anything. It was an intentional design choice to leave the screw driver loose because it doesn't have a slot in the interior packaging to fit into (same in both units I ordered). The back of the product did not have these same scratches which makes me suspect the screwdriver even more.The inside of the product also has several scratches in the metal (see pictures). Some will be covered up by letters while some will not. Some scratches appear to be from someone opening and closing the unit at the factory (they were there from when I first gently opened it). But other scratches look like someone was just careless with their tools when fabricating the product. Perhaps use tools made of a metal softer than 304 Stainless so it won't scratch by accident.For the price I'd expect better quality control. It will get the job done, but given a choice I'd prefer a product that looked as sleek as the Amazon listing photos, not beat up units that look like a small dog with metal teeth chewed and clawed on them.1 star for delivery speed 1 star for able to do its intended function 1 star for all parts being included 1 star for good price - 1 star for the scratched up metal = 4
