To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
Usually when a seller advertises the item as "International Version" it means European/unlocked model (for OnePlus 7T Pro, it would be HD1913). What I got instead was a Chinese model (HD1910) with a different ROM. In actual use there's very little difference, but Chinese models with international ROMs are usually $100-$200 cheaper. So the product itself is fine, but wouldn't recommend buying it here
