Please be aware to by any GPS devices from Shenzhen ET-Safe Teachnology Co.LTD., (http://www.et-safe.com/), this company is totally fraud, unprofessional, and sells junk devices.
We ordered 2000 pcs of ET106 trackers(Sales Man: Kaven Wang, Skype ID : ET-Safe), they assured will send tested devices and after sale support for devices along with 1 years warranty. They did so many basic mistakes in International shipment (wrong currency mentioned in invoice, no record for IMEIs they sold, etc) that it caused us 2 months delay to get custom clearance apart from heavy financial penalty. That was not it, after we found the shipment and tested it, found all of the product faulty, having manufacturing defect and totally junk. They has already taken complete money before dispatch.
Now they are not answering our call, email reply. Et-safe company should be banned for international trade, please beware before you by. This company is a group of thief's and fools.
