great product - this time the shipment took 1 month. they claim it's because of voiding the tax, and that's it's not true, cause I pay the tax in my country everytime I get packages from china. the Alibaba logistics is not good, because you can't track your order correctly, don't get any notifications/email/sms - only internationals shipment company can tell precise where you package is.
all of all, they never offer refund, not only this supplier, Ali baba is always on the suppliers side, even if you are right.
