Review: Sturdy, high quality - I suspect mine was a returned item because it wasn't sealed, nor was the device properly inserted in the box. Shame on desertcart for selling something like that! But all of the parts, including the three plates containing the letters, were intact so there was no point in returning it. Everything was easy to set up, albeit time consuming since you have to punch out each letter of the words in the seed phrase and carefully insert them into the slots. The plates are strong and robust. The supplied screwdriver easily removed the screws and each plate slid apart with no problems whatsoever. Once the letters were inserted and double-checked, the plate covers went back into place and the screws reinserted and installed easily. Just a note for complainers who don't read instructions (which they probably won't read this, either) and slammed the device for only having space for four letters per word when their seed phrase words contained more than four letters: all you need when entering the seed phrase is four letters. It clearly says that in the product description and if you look into the BIP-39 or BIP-44 standards, those verify that fact. The only negative thing I have to say is that the "i" tiles look very much like the "l" tiles and you have to look closely to tell them apart. I wish they had separated the dot in the "i" more.
Review: Strong - Spectacular! Very sturdy and quality product.

## Features

- [BIP39 Wallet Supported: 12/18/24 Seed Phrases] Compliant with the BIP39 mnemonic word list, where the first four letters of each of the 2048 words are unique. You only need to record the first four letters of each word to accurately restore the full mnemonic phrase, simplifying the backup process
- [User-Driven Design: Thicker and Tighter] Don’t worry about the seed phrase being moved or out-of-order after tightening the tile. We made the plate thicker than others, and provide sufficient screws to tighten your recovery phrases
- [Laser-Engraved Characters] The characters are laser-engraved on the stainless steel tile, which is smudge-free, fireproof (It resists temperature up to 3632°F/ 2000°C), waterproof and anti-corrosion. Keep the seed phrase safe forever and ever
- [100% Hacker-Proof Physical Security] Non-electronic design ensures no risk of hacking, providing an ultra-secure, physical backup solution for your cold wallet
- [Equipped with laser-engraved letter blocks] that provide clear and durable markings, preventing blurring or wear over time or due to environmental factors, ensuring long-term readability
- If an extreme situation occurs where alphabet blocks are insufficient, please contact our customer support at support@imkey.im for assistance.
