Concox 3G GPS Tracker for Car/Truck/Motorcycle GT06E with Acceleration Sensor, Remote Control Cut Off Power/Petrol,SOS Emergency Call and Multiple Alarms(One Year Platform Use)

Fantastic product. Very easy to install. I used a 1pmobile SIM card and worked straight away. Didn't like the fact about the Tracksolid app being so obscure to register (it has to be through the seller). But even with this, you can't expect any more for your money. The thing works by SMS and trough the tracking platform. After a couple of days of use I have estimated the SIM top-up cost to be lower than £10 a year. Documentation could have been much better, but is enough for someone with basic knowledge. Seller was quick registering the device in the platform. Definitely will buy again. Very recommended.
