A Chongqing-based company that operates an outcall tech service across most of Shanghai. They'll repair most Apple products except ones they deem "too new," and a host of phones (Oppo, Vivo, Huawei, Samsung, Meizu and Xiaomi). For laptops, they'll collect it and take it to one of their two service centers for you. The website's fairly easy to use and they also have a handful of English speaking technicians you can call and arrange for. There's no door fee (unless it turns out nothing needs repairing, then there's a 49rmb "consultation" fee).
