A correct but not extraordinary autonomy (the tablet is new): Approximately 3:30 in public wifi (download, update or use Dezeer) and few other of applications installed the antivirus .. or 5h for use without WiFi.
It is fast and not even plant after installing dozens of applications to test the suites.
Having already had many problems with the Acer brand, I still recommend this tablet because it works really well (for now)
Small disappointment for the lack of a dedicated power outlet, leaving the mini USB for a key or otherwise.
No mini usb adapter.
No detailed instructions for this tablet and too imposed and not uninstalled software although there is space in the internal memory.
Resuming comment a few weeks after purchase:
If I add anything on machine performance which are excellent for the price, I would add that this tablet is poor in terms of the connection WiFi.
I use a lot of Free Public Wifi and whether the computer, the smartphone and tablet even bought on sale at 29.50, all perfectly capture WiFi.
This Acer mostly can not be used for public Wifi and when it connects, it often disconnects after a few minutes.
