Been using the Trezor One a couple months now and I am extremely happy with my purchase. First of all their hardware and software is intuitive and works smoothly. The device setup process and their wallet is user friendly, even for beginners. I rest assured knowing my coins are safe. When I wanted to explore other coins (ETH, LTC, ERC20 tokens) it turns out the Trezor wallet has built in support for it, so they can all safely be stored on it at once. They have a lot of useful information on their wiki, when you inevitably have a question. Overall, a great deal for a smooth experience. Protip: make sure to buy from the official Trezor.io website and not a reseller for optimal security guarantee.
