I have been experimenting with different signing devices (wallets) and wanted to share a tip. ₿efore you send anything to the SD delete and reinstate it using the passphrase. This way you know for sure you can do it. If something does go wrong you are not panicking. I find I am getting used to self-custody of my ₿itcoin and still get the jitters moving large amounts.
If you have any other tips they would be greatly appreciated.
