This statement was released by KeepKey on the 22nd of Febuary:
It has been brought to our attention that a small number of units from a substandard batch of KeepKeys have been shipped in December.
Affected KeepKeys lacked protective film and had sustained scratches to the screen. This has caused concern with end users that the units had been tampered with.
We would like to reinstate and guarantee KeepKey never sells refurbished or used units. KeepKey has taken steps and placed stricter policies on manufacturing processes and quality assurance teams to ensure all KeepKey units have high consistent standards. Any units that fall short of these qualifications are disassembled.
We sincerely apologize for any inconvenience that this may have caused.
If you were affected by this bad batch of KeepKeys, please reach out to our support team, firstname.lastname@example.org, and we would be more than happy to send you a replacement right away.
