The metal frame of this wallet is very strong (my friend has this wallet). In appearance, it is quite similar to a flash memory, and of course, this metal frame makes this piece more protected from shocks, which is a good feature.
One of its good features is that it can be connected to myetherwallet, and for people who use MEW, I definitely recommend this wallet.
Another good feature of ledger nano s, which is a much better option than online wallets, is that two keys must be pressed on the device at the same time to confirm transactions, which means that even if someone hacks into our computer. He can not transfer money to his wallet because we do not select these options.
