Seems decent for the money. Someone mentioned this as am alternative to the Xiaomi Air 12 I'm this thread: http://www.hotukdeals.com/deals/xiaomi-air-12-laptop-banggood-for-398-22-2632526
Personally prefer the look of the Xiaomi but this is a UK seller, comes with English Windows (8.1 vs 10). Specification looks alright though not stunning for the price. Colour is white. Don't know the seller but Trustpilot reviews are very favourable.
Posting from mobile so apologies for brevity.
