honestly, it's a pretty well built knock off. Yes, there will be people saying for US$50 more I can get the real deal. But how often does the real deal comes along at sub US$200 price? Then again the GG will not be the GG if it's produced like 10000 pcs a day in a factory in Shenzhen.
There the tangible value and the intangible value to things. It's just how attached are you to them.
