for me it is, The Ledger Nano S is a product of a France-based startup. It has sleek and attractive European touch to its design.
Some of its core features are the backup seed key for recovery of your bitcoins, the easy to use OLED interface, and a flash drive like feel with two buttons on the side for navigating the interface.
It is a battery-less device which you can connect to a PC or mobile device via USB. The Ledger Nano S now supports nine cryptocurrencies (including Bitcoin) and is also the cheapest multi-currency hardware wallet available ($65).
