Bought 2x 11200mAh from this bro. Contacted him at 11.30am on 29/7/12 to enquire for the final price and COD'ed with him at 12.30pm, 29/7/12! lol yea, got the transaction wrapped up within 1 hour! Hats-off to his attitude in doing business, definitely highly recommended! I've also checked with yoobao website and both of my battery banks have been certified to be original. Happy dealing with you, mr cheong!
