I use a Ballet Wallet I ordered on Amazon.  I trust it based on the historic integrity of the company's founder.  I researched and listened to a couple of his seminars on YouTube.  In addition, I am not aware of anyone who has had a security breach due to the companies manufacturing process.  It seems to me that his company's success and reputation as well as his personal reputation are at stake.  In other words, if there were a security issue that was traced to the production process his whole business model would implode.

The one issue that I am still trying to resolve is how to back up the Ballet Wallet.  I've seen a hardware device that uses metal plates to engrave a key code based on the words you used.  The idea is that they are indestructible by fire and more durable than paper.  However, since the ballet wallet is not using words any backup methodology using words will not work.  I am a little concerned with the fact that if anyone were to get physical possession of the wallet, they would have my bitcoin.  If I bury it somewhere or hide it and die then I can't pass the Bitcoin on to my family.  So, I am open to anyone with ideas on how best to back up the Ballet Wallet.
