I saw a couple of references here and at one of the Bitcoin magazines to opendime, a Canadian outfit making a cheap, one-use-only hardware wallet. It looks pretty interesting to me, but the website does not make it crystal clear how to take your BTC out.
https://opendime.com/They have sold their first batch, it looks like more are on sale for delivery soon (June/July).
It looks like they accept Bitcoin as payment now.
Has anyone tested the product?
