I picked up a Redmi Note 3 (the one with a hex-core Snapdragon and 32GB storage) earlier this year whilst in Singapore. Very fast, nice screen, decent GPU, outrageous battery life, decent camera, dual sim system works well... honestly, I love the damn thing but as of yet, I haven't been able to get the latest update to work. It just keeps saying update failed
I mostly use it as a work phone, and I have had a lot of time off, so in fairness to the phone I haven't really put a lot of extra effort into sorting it out yet. Im sure I will get it figured out.
I would definitely recomend the phone to anyone who is a bit techy, but otherwise, stick to UK models.
