AG Mobile's devices have by far proven to be of fair quality looking at some of their previous range of both smartphones and feature phones. The quality vouches are however almost always unclear when dealing with new device designs. You can however be of good cheer as all AG devices must come with at least a minimum of 1 year warranty - which means that if it fails (these exclude failures owing to the owner/user's neglect, mistakes or intent), withing the warranty period, then you get a free replacement or service. Do take a look at AG Mobile's Life Time warranty sometime.
