Some already pointed out that only those who have problems reports their anger on the internet. This may be true, but IMO not on a forum like this one: Users have been active before their orders. Many ordered several devices and reported their problems for those running as well as the defective ones, as a feedback on what was looking as a bargain at first (and for many, was not in the end).K3rryBlue wrote: Sure there might be some defects, but this is related to all brands even the A-brands.
I start having many devices, none of the A-branded ones failed for now and I have a 2 years waranty. 50% of Neo did very quickly. I don't think the remaining will last for long and buying in China = in practice, no waranty after product delivery confirmation (My advice: Confirm delivery a few days after, always better to convince seller to refund if confirmation not done).
That's my own statistics and many other can exhibits the same. These facts have to be told, so others can make their mind.
