I received a broken USB headset. My phone does not detect it when plugged in. It is totally useless. I asked for a refund or exchange as advertised ("Free returns within 90 days"). Support denied my claim, saying "not enough proof" even after I sent photos and videos. They ignored their own return policy. I got no help and still have a faulty product.This seller and AliExpress support do not keep their promises. Do not buy if you want customer protection.
