Other: Great thing. Easy to use. It does have necessary functionality for me.

Pros: Tracker automatically installs Internet settings when you insert sim card. Sufficiently sensitive receiver works even bordachke car.Managed as a phone call or SMS message here. Through the Internet can send their location on a special website. stores the history of the route and current location tracker. There is a mode shaking when he triggered an alarm and sends the coordinates location or direct link to Google maps

Cons: There is no feedback to the site, where the coordinates are passed as support. If you lose your password. No more disadvantages.

Other: Good simple tracker.

Pros: Well, it's really great gadget. It works fine with good accuracy. It saves gprs traffic when its not moving, it has a big sos button, so you are not able to miss it. I've used other models of trackers before, witch has a small sos button, located near power button, so, it was easy to push wrong button. This tracking device is responding to all messages that it gets.

Cons: Sometimes vibration sensor is not working. It was hard to find documentation with TCP/IP protocol of it, so it took 3 days to find it with active googling.

Other: Cheap, good quality, perfectly-working, must have gadget!
