Verdict

Please note that we do not yet own a Blockstream Jade. Our verdict currently is based on available online resources only. We love the 100% open source approach and can’t wait to get our hands on one.

If your use-case is Bitcoin ecosystem only, this seems like a very good option to secure your valuable Bitcoin assets.
