The recovery service that they've got is applicable to the newer versions of their hardware wallet.
Avoid if you are just about buying a new hardware wallet. As for safe, if you were already using Ledger before they announced the Ledger recovery service, you might just continue using it as you have been doing so, but of course without 'subscribing' to the new Ledger recovery service, but whenever you decide to get a new hardware wallet, you should ditch Ledger for a different brand; because there is then no reason to continue using it.
This is right, if you own the old Ledger Nano S version, it's not part of that recovery feature. As for the choice, I guess that on these times the favor goes to Trezor.
I have the same version so I would prefer this kind of model than those that supports recovery feature. But to be honest, I really do not like the decision of Ledger to include the recovery feature for the updated versions.
It clearly not defining them anymore as a true cold hardware wallet. I don’t have any plans to buy future versions of Ledger Nano like the X or so because of the controversial recovery feature.
