Chuwi is a SCAM!
i bought a pc for 400 euros. received it promptly all working ok. after about 5 months it just did not start up anymore. emailing the after sales did not get a reply. after around 4 emails i finally got a reply with a address in Germany to send the pc to ( paid the parcel costs myself) after a month still no confirmation having received it. after many emails they finally confirmed having received it and asked for 6 weeks to repair it. It has been 5 months now. they never reply any emails. Only through facebook messenger they reply and apologize and say they will send it back asap. But they never do and they never contact you. It is a scam, they steal your pc and your money. I hired a laywer but as they have no physical address in Europe ( the german address does also not exist anymore) it is hard to sue them. Stay away from Chuwi, bad quality and no guarantee or service.
