Packaging
The product delivered in a well covered box and there was no sign of bad transportation.
Physical View
There is really no word to say for the physical view of the product.
Running
The supply works with no problem. I read the various voltage levels and approve that the voltage drops under load are as much as low. It means that the voltage stability is very well.
Conclusion
I am not a power supply man 
I do not know how a power supply should be, how a load test should be done and how its efficiency should be determined. But, at first sight, i can say that it is really a quality product.
When i have a chance to test it under full-load and over-load, then i will update my review.
