If the board looks the same and there is no evidence of any modifications, they should be ok. Also, if it connects with genuine versions of Ledger Live that you downloaded from the official website and not a fake one that you were instructed to use with information in the package, it's a sign you are using a real Ledger. We are yet to see a fake/modified Ledger that can connect to Ledger servers, install the needed crypto apps, update the firmware, etc.
Correct. That's why the only way for scammers to abuse a hardware wallet is either to make a seed and hope the buyer is dumb enough to use it, or connect their own data storage straight to the USB that works alongside the wallet. If the board doesn't have an sd card or something soldered to it and the wallet passes ledger's checkup it should be OK to use. I've never seen a modified hardware wallet where the attackers replaced the chips so that the board looks the same at first glance but has completely different data on it.
