No point getting those china clone, most quality sucks.
I've used for a few days, its very good at 4:3 viewing and touching etc..
Size wise like ipad mini, so casing is not an issue, there are plenty around, and if u find the button can access, u just need to do some cutting.
Battery wise is good. Use whole day surfing still can left 50%, I don't even need to charge for another day to use.. Wifi is good.
This is the first time I bought something within 1-2 days because most of time take me months to decide because I many gadgets out there have some flaws.
Its very light and slim like ipad mini weight 30g different.. Only 7.2mm, the slimmest on the market. Chuwi is 8.2m.
Don't get those heavy casing, what's the point if u want light stuff to carry anyway. GET valore ipad mini casing, its very light and the holding feel is good together with your mobile phone.
Just open tether to your mobile phone with 1 click using tethering widget. another 1 using wifi widget. instantly gets you connected for web access etc.
No bluetooth or 3g is ok, since mostly using for web surfing and reading... if needed just plug in earphone.
anyway using bluetooth will drain your battery even much faster, then it didn't serve the first purpose in the first place.
