I baught a ZGPAX S5 1.54" Touch Screen Dual-Core Android Watchphone with free shipping, after more than 20 days, It arrived and it worked in good condition but the earphone did not work properly as there was no sound input from the left bar. I left the message to their customer service and sent a RMA ticket, in 3 days, i got a tracking number for a new set of earphone parcel delivery. That is really amazing service. I got many bad afterservice from online sites before and that is the first time to satisfy me.
