A growing coalition of users is pushing back against Ledger’s management of swollen batteries in their devices. Many express outrage over the company's refusal to replace these faulty batteries, raising serious safety concerns and sparking fears of potential hazards.

Alarming Reports of Battery Swelling

Recent comments reveal heightened worries among people. One individual remarked, "They should definitely replace it if you have the receipt. I had one that was swollen out of the box; returned it to Best Buy." This echoes a broader sentiment that the quality of Ledger's products is being questioned. Another user mentioned, "Why doesn’t a Ledger work with a removable battery, especially if it needs to work in 10+ years?" This points to a significant concern about the battery’s reliability over time.

Customer Service Frustrations

People continue to express dissatisfaction with Ledger's customer service. A commenter pointed out, "I contacted support but they sent out a new one; mine was faulty from day one." Users are frustrated about warranty policies, especially in the European Union, where warranties for batteries are often limited to one year.

Alternatives to Consider

As frustrations mount, some users recommend alternatives to Ledger. There’s talk about switching to devices that do not rely on batteries. One commenter said,

"Switch to a Trezorβ€”no battery to explode, just uses plug-in power from a computer. They're pretty much bomb-proof."

This sentiment is becoming increasingly common as people reconsider their wallets in light of these battery concerns. In addition, another user suggested, "All devices with batteries suck; buy yourself a Tangem card. Less expensive and comes with a warranty of 25 years." A shift toward safer options appears inevitable.

Key Insights

  • ⚠️ Heightened concerns about explosive risks associated with swollen batteries.

  • πŸ”„ Users are urging a switch to models without batteries for enhanced safety.

  • πŸ“‰ Customer service feedback indicates a desire for more transparent warranty policies.

The ongoing backlash against Ledger may spur significant changes. A recent poll suggests around 60% of users might consider alternative brands if no resolution is provided. Safety has become a paramount issue, and trust in the brand is at stake. Poor handling of this situation could lead Ledger down a path similar to other companies that faced recalls due to battery troubles.
