A growing group of crypto enthusiasts expresses frustration over Trezor's Metal Keep device due to a four-letter word limitation in security seed phrases. This concern could impact purchasing decisions, as many users hesitate to commit to the product amid questions of security and usability.

User Reactions and Misunderstandings

Each word has unique first four characters, ensuring your wallet knows the exact word when you enter these letters."
