What is the difference between V9 Pro and V8 Golden?

What is the difference between V9 Pro and V8 Golden?
V9 Pro (HD) is another name of V8 Golden, same design, same hardware, same software, same remote, same wifi adapter, same power adapter, and same price, all completely the same except the logo.

Why we make 2 products since they are the same?
V8 can be used for other countries, while we install the customized software(with our server) on V8, it can watch all Star-hvb channels, to make box different from other countries’, we decided to give it a new name(V9 pro).
The tuners for V9 Pro and V8 Golden are different.
Some V8 golden may not watch 277-233,  but no problem for V9 Pro at all.

So it is V9 Pro = V8 Golden + customized software
