Acer Iconia B1-720 is an exceptional tablet at low cost. It is better designed/built than others of non-brand name.
It is one of the few with 1GB dynamic memory (most only have half at this price). 8GB flash memory is excellent, and micro SD can be used.
Dual-core 1.3GHz processor is plenty quick. 1024×600 capacitive multi-touch screen is clear and has excellent contrast.
199x122x10.7mm is thin. Lithium-ion 11.2W.

This looks nearly the same as B1-710 (which I also own), but it has a quicker processor, larger room battery, front speaker, and slight physical difference.
Most tablets have rear or bottom speakers, so this front speaker makes the sound louder and more clear.
The power button is now at the top side, and the volume buttons are on the side, which prevents accidental power-off trying to change volume.
Unfortunately the buttons are now flush, so they are trying to locate and to use. This is the only negative issue with this tablet.
If you use the volume buttons often, get the B1-710.

Buying cheaper tablet is somewhat risky because the build quality varies quite a bit from unit-to-unit due to varying quality control at lesser manufacturing facilities. This one is worth it.

Finally, I get my new Acer Tablet but once I started using it I noticed that the battery was no charged then I chose to charge it in order to start using and surprise, 5 minutes after it was 73% charged, yes, the battery is not working as fine. Once it was “completely” charged I started using it and 40 min after it was asking for connect the device to be charged. This item is junk and to try to return it is gonna be awkward.

Is an exceptional tablet at low cost. Upgradeable to Android 4.4 Kit Kat through WiFi.
