Nano ledger s is really secure. Totally invulnerable I would say

That's dangerous thinking... NO solution is 100% secure and it is foolish to think as much.

It has already been proven for both Trezor and Ledger Nano S that their solutions have had security flaws...

Granted, they've both now been patched to fix those flaws... and no doubt another round or three of security auditing has happened since... but I, for one, would not be making such bold statements regarding the security of ANY wallet.
