Wanted to purchase this for someone I know. Had been waiting for a 15% off for a while. On eBay I could find only 10% off deals. As per website there is counter for expiry, but based on comments looks like it's been this price for a while.
Detailed review here
Update:
This can also be bought for same price from their official eBay store for $849.15 using the 15% code P15ACE
How much better is this than the first Gen xiaomi ones?
