Have used the Ledger Nano S before and as far as the display is concerned, I can only agree with the OP. It is very cheaply produced and does not last long. After the display broke, I have no longer used a HW wallet.
You can easily order and replace that display yourself, order it online from from one many websites that sell them like
this one for example, and follow this
video instructions.
If you need any help you can write in this topic, and people will help you if you get stuck somewhere during this process.
Ledger should also release new device ledger nano s plus in 2022 and they improved display and made it bigger.
But I am about to buy a new HW wallet. What do you guys think is the best option right now? The software should be open source and the memory should be enough to manage at least 10 coins. Is Ledger Nano X a good option?
I would not suggesting anyone to waste money purchasing ledger nano X for several reasons, it's closed source, many people recently reported battery and firmware update issues.
More information about this can be found in my topic
Ledger Nano X Battery Pandemic.
My suggestion for everyone is to think about purchasing and supporting Open Source hardware wallets, or simply use offline computer with software wallet.
List of hardware wallets supporting more coins like you want:
-
Trezor-
Bitbox-
KeystoneI had some of the same Ledger concerns shared in this thread but to me they are absolved if you're willing to buy 2-3 wallets at a time and shelve/store them securely after verifying they work. I didn't like the data breach Ledger had but these things happen, even to governments. Batteries and screens also fail over time, no electronic device is exempt to it. I want to be clear that I'm not knocking open source here either though, I'm just saying I don't share the grave concern here as to why Ledger is that bad in comparison to other options out there.
However, with the above in mind and if I was buying right now, I really like the way Keystone is going, especially when it comes to the issue of batteries issues over time.
Lastly, no way I'd use Ledger for FIDO and I don't suggest anyone use any hardware wallet for that purpose either, simply because you're putting too many eggs in one basket if you ask me.
