[Q] Better to go Chinese or wait for an invite? topic

Here's the situation, I want to buy this phone for my mother so I though I'd take a look at amazon UK as they had sellers listed as OnePlus themselves but I was suspicious, after some searching I found they only sell the chinese version on amazon which I've heard has more problems
I don't know a single person who owns one so getting an invite is kinda....impossible.
Should I settle for the Chinese version or scour the internet till I can get an invite, time is important here as she needs it for work.
