This is the Xiaomi Redmi Note 3 - the latest in Xiaomi's line of 'budget devices'.
This is budget devices on another level though - the Note 3 packs a Mediatek Helio X10 processor, PDAF 13 Megapixel camera, 32GB storage, 3GB RAM, a 5.5" screen, metal unibody, fingerprint reader and a might 4000mAh battery. All for well under £200 imported!
We're going to be putting the device through its paces, but in the meantime, do you have any questions? Fire away!
