I tested it very well. For every 5 hours charge it gave me like 28 pages of reading, said low power and then shut down. Max. it gave me was just 150 pages. Last time, I charged it for 5 hours and it gave me 5 pages of reading before shut down.
Got NO support from manufacturer. Returned it to store and Manager gladly took it back, was very happy with my feedback. Luckily I purchased this in person and would strongly advice all here to stay away from this product, specially NEVER buy this over mail. Also, stay away from all similar rebranded products. I lost two days with this product, time is also vital, it is better spent reading or even going for a walk rather than having to deal with poor devices.
It is far better to get a good eReader with eink technology. If color is desired, please get a Netbook.
