Is the k6 reliable in Shanxi? How can I verify the authenticity of a k6? I checked the QuanSheng official account and was told to look for anti-counterfeiting labels. However, I didn't see any such labels in the battery compartment of mine. Is it possible that it's fake? (PS: The radio is not mine; my friend bought it on Pinduoduo. We both like radios. Last week, we took an exam for "a". After the exam, we planned to buy two radios and assign roles. I passed, but he didn't. 😀😀)
