Do not buy this product, I purchased in August 2021 and it work fine for about 3 months when sound stopped working and  Blue screen appeared . CHUWI replaced that Laptop and now second Laptop has no sound after only a few months of use. Chuwi support send a link to reload sound drivers but it does not. However, the worst part of this is that Chuwi support has completely stop answering my emails. The say that they will answer support requests in 24 hours well that is completely false. At this point I got Microsoft to help reloading windows 10 but that did not fix the issue. At this point I am completely lost because CHUWI support will not help. Only buy if you need a laptop to work for a couple of months because after that you will be out of luck.
