Growing Frustration Over Quality

"Buy a new one. Or any other wallet you trust," one commenter urged, highlighting growing distrust. Encapsulating the turmoil, another stated, "They should definitely replace it if you have the receipt. Itโ€™s a product with terrible quality." Some community members praised replacements, noting they don't require the faulty unit back if clientele present a purchase receipt.

Reflecting on Alternatives

Interestingly, users are suggesting alternatives to Ledger. One commenter stated, "Switch to a Trezor, no battery to explode." This reflects a wider trend of users seeking safer options amid the swelling battery concerns. As one user lightheartedly remarked, "Looks like you have too much crypto stuffed into your wallet."

Highlighting Safety Risks

The safety of Ledgerโ€™s products remains a top priority among users. "STOP plugging that thing in now!" urges one user, cautioning against further use of the devices.
