I'm very happy with this device. It works perfectly. But getting it up and running was not a cake walk.
The problem with this tracker is that it has a lot of features and each one has its own wire. So, what I did is I took a pair of scissors and I cut off all the wires for all the features I didn't plan to use. That left just two wires--the ones that connect to the battery. If you keep it simple, it works great. If you want to try out all the features, you better be another Steve Wozniak.
This is actually two trackers in one box--GPS and GPRS. Forget about the GPRS, the cell tower triangulation. It's sometimes wildly inaccurate and getting it to work right is complicated and frustrating. The GPS, on the other hand, is very accurate and the set up, with default settings, is simple and works great.
The tracker needs a regular size cell phone SIM. A lot of users get the T-Mobile SIM. I would recommend getting the H2O SIM. It's cheaper. Also, if you get the T-Mobile one, you'll have to put it in a cell phone to read a text message that they'll send you to set up your account. Save money and hassle and just get the H2O SIM.
The instructions aren't the best in the world but if you're setting it up for simple tracking, they're OK.
I installed mine under the hood of my car with duct tape. It does just fine in the heat and it won't drain the battery. My car was sitting for two weeks straight with the tracker turned and it didn't drain the battery so the power consumption must be very low. The two wire antennas it has, for GPS and cell, I strung up under the windshield wipers. That gives it some exposure to the sky and yet it can't be detected.
If I want to know where my car is (people borrow it), all I do is call its cell number on my iPhone. The tracker then sends me a text that says where the car is, how fast it is going, and in what direction. When I tap on the text message, it goes straight to Google Maps and I can see where it is. It's that simple.
I've called the tracker over 100 times and it has received my call and sent me the location 100% of the time. The failure rate is zero. The accuracy of the location is almost always within 20 feet. Not bad.
So I highly recommend this tracker as a device that is rugged, accurate and reliable. But if you want to try out all the bells and whistles, good luck.Rating: [5 of 5 Stars!]
