Hi,
I recently bought an OnePlus 5T on my vacation in China. My old phone was the OnePlus One, so if you are in China and want an OnePlus you should consider to buy it there.
It cost me about 450€ and the normal price is 560€ for a 8GB RAM with 128 GB storage. I bought the red lava version because is only available in china :-).
I bought it directly in Shenzhen where the headquarter of OnePlus is. The only problem is that are no official store you can buy it, so I have to buy it on one of the malls there. Not everyone knows that brand and even the phone though it comes from there. I was very confused but if you ask they will sell you one or more :-). The only problem is that they have only a China version and you have to flash the oxygen os from the OnePlus site.
So far I am very happy with that phone. I like the camera the perfomance and the operating system on it. OnePlus did a great job again. If you need more information just comment my post.
Thanks for reading.
