I've been looking for a solution to seed storage for a while and settled on holdr swiss because of it's excellent fire & crush resistance as per Jameson Lopp's reviews.

Build quality is excellent, heavy substantial feel. Kudos on the the well thought out setup process with easy to understand documentation.

The device is beautiful and my only lament that it can not be put on display :)
