Had mine since Sept 15 and still working fine. Good little tablet for the money. Occasionally has the odd glitch with bluetooth in Win10 but nothing significant. Works very well in Win 10 using the 4 port USB Charger HUB cable which cost less than £7.
Have had my Chuwi Hi8 for about 4 months, no issues yet. Charge it and use it every day. Also looking at the Hi8 pro for the GPU upgrade but from what i’ve read overall performance is very similar.
