This Ledger battery that went bad at the beginning of this year—over the past couple of days, I suddenly had the idea to reach out to customer service for after-sales support.

Because I bought it earlier from a third-party authorized retailer in Hong Kong, when I tried to get after-sales service, I suddenly discovered that this website had already gone 404.

So then I went to Ledger’s official after-sales service.

I’ve been using this Ledger for almost two years. The after-sales team promptly sent me a new one, and they didn’t even ask me to return the old unit.

I’ve got to leave a good review for this—haha @Ledger
