For the price not bad. However, if you on the lookout for special offers from time to time, you get brand quality at a similar price. The disadvantage is actually just that is somewhat limited viewing angle: one must be able to detect even vertically or something from the bottom look at the screen at all. The resolution I find good enough. The telephone function is appalling: works, only the voice quality is so bad that seldom enters a communication state. A headset makes no difference.
