Thanks for the reply Nasosak, it seems that this is a good tablet, but now I saw that they started to sell the onda 975i, which looks interesting with Retina screen and bay trail CPU , too bad it will take a month or two until we'll get trusted reviews .Well, I usually play around with the tablet for a total of 9-10 hours, before I re-charge it. Mostly 2-4 hours per day, googling, forum reading, playing games, watching videos with my son.
It has got an extreme standby losing 1-2% overnight (closed WiFi).
Screen is bright enough, I have set it to 0 brightness and still bright enough. WiFi is working fine.
I can say it's a very good choice, and I have used a lot other android devices with other CPU's.
