Hi Tioo1212,

I checked your device's serial number, and unfortunately, it doesn't appear in our database, which suggests it might not be an authentic Razer product. To avoid issues like this in the future, we recommend purchasing from authorized Razer resellers. This ensures you are getting a genuine device. Please note that products from non-authorized dealers, as they might be used, counterfeit, re-boxed, defective, or gray market items. If there's anything else I can help with, feel free to reach out via PM. Take care!

Post a photo of the bottom of the mouse. It may be fake.
