However, I would like to emphasize that the most important job of the backup and screws is to protect the seed inside the unit, so it made a pretty good job, even if a bit hard to remove. After a house fire or collapse, I would be most interested in backup survival, even if I would need a hammer or power tools to open it.
Yeah I agree, important thing was protected and every product can always be improved, so I am glad that you fixed small issue with screw already.
I think next step you should make for Coinplate is to work more on marketing, and maybe making some partnership with other products like hardware wallets.
