You are protected by the Ebay Money Back Guarantee if the phone is not delivered or if it arrives and is faulty or not as described in the listing.
You have 30 days from receipt to open a case and return it so make sure you are happy with it as soon as it arrives.
You are no more likely to be scammed by a seller from Hong Kong than a UK seller (in my opinion).
"There are two ways to be fooled. One is to believe what isn't true; the other is to refuse to believe what is true.”
Søren Kierkegaard, Danish philosopher (1813 - 1855)
