Samsung Galaxy Note 5 Fake or Real

Hello folks. Today I go across this nlo... -  Samsung Galaxy Note 5 Duos SM-N920CD (FACTORY UNLOCKED) Dual Sim - Choose Color on ebay
 I doubt the authenticity of its origin! But it stated right belove title this "about details"

✤ FREE GIFTS & FedEx 2DAY ✤ Real USA Seller ✤ in Stock

 Does not believe that this is real deal on ebay, I made my search all the way from high to low and catch my eye in six hundred ones exact on this one it stated in title DUAL sim that mean your phone will work of two provider, with is probably something that not allow on US land by FCC and FSC
 I assume it is came from mother China, last year I noticed in Russia visit in the phone store, that they have Samsung and LG at the most, and each phone is Dual SIM, so you can use two providers at the same time..
 Anyway I look at the Feedback of this seller, and decided read Neutral, because Negative peoples left at when they get vicious!
 here is the comments:

Feedback	From	When
	Received a used phone. Sent it back and got refund from seller. Wasting time.
	everything like described but object doesn't work properly
	nt bad , but phone have small problem
	had to do hard reset for it to work not sure if its use phone just be careful--
	missing a few items but they sent
	Wasn't brand new ,,, refund process was slow .
	i am not satisfied. phone is looking like someone used before
	Ad said "Factory Unlocked" but signal very week on T-Mobile and Ultra
	I settled with inferior specification with partial refund
	But battery bad. Only for 2hours. I think you know about that and sell it.
	cell battery is very bad.
	Seller claims border agent opened & tested the phone but offer refund or replace
	Defective device. The seller has refunded my money, but was a long slow process.
	the device battery is too bad, can you explain why your device not like others?
	Sent out open box phone , buyer beware!!

I think these phone are legit for other country, not USA, in that country Hynday Accent 300kg is lighter then the one we have in US and they assembled  these car on there land! So the phone's has made for them is well, but not for USA
 That why we see in comments that ether battery is fail work properly errors etc., and overall it is look lot cheaper.

So watch when you hunt that way!
