This depends upon the price, recently I have bought Zenithink C92 tablet pc with 10 inches screen and let me tell you that the product is simply amazing and chinies are doing very well.
My cousins have bought 7 inch Onda on trip to China and had been using it for past 3 months. So far very satisfied.
See, the reviews which I have read are that Chines lacks in Software but have excelled in producing a quality hardware. In this case, the operating system is Android which is free without a license need. So end result is that they are doing very well as they don’t have to worry about software.
You can get Zenithink for USD 160 plus shipment charges.
Recommended and check the prices on aliexpress.com before buying.
