I had no troubles with delivery of goods which have been ordered.
All $#*! comes when one of phones purchased starts malfunctioning four months after delivery. As i requested customer support, i have received an answer that this model is out of production/sales already and no way to repair it...
I came to the site and easily found this model available for ordering.
After series of mails took ~3 months in total, they finally offered me to repair it, but under condition that i will pay extra money for any part that will be changed.
For my argument that this approach is not a "guarantee" by definition, they react with typically chinese elegance: stopped to reply to my mails.
Bottomline: if you are ready to buy something which can broke next day and refurbishment will be done at your expense - go forward and buy at www.achinaseller.com. You will never have your guarantee executed and will never have money back.
