EC-B Series Noise Issue Announcement
Brand & Product / 2018-02-06
There is a small percentage of EC-B series mice that produce a noise which in quieter environments might be noticeable to some users. The noise is caused by the high frequency vibrations of the 3360 sensor and other internal components. We have since addressed this issue and are deeply sorry for any inconvenience caused.
Please rest assured that the performance of the mice are in no way affected by the sound. Strict regulatory testing has also been done to ensure that these vibrations are harmless to the human body.
Your comfort and satisfaction matters most to us and users who are bothered by the noise may contact the BenQ Service Center for further assistance. Replacement is available now. The reason for this timeline is because we have enhanced our test procedures during production to ensure this issue does not reoccur.
Once again, we would like to sincerely apologize for this inconvenience. Thank you for your patience and understanding.
