Beware of this because they might not tell you now. They have to install the gadget in some hidden place (does that sound familiar?),so that when the gadget has a problem you have to visit their workshop after which you will be bombarded with a surprising invoice + VAT for 'servicing'. Secondly,the gadget sends you the vehicle location in terms of geographical coordinates only. E.g. 39S 15E 0' N. In case of a theft,how do they (or you) expect to interpret where this could be on earth?. All gadgets work like this. The only difference is that some have invested heavily in software that interprets the above coordinates on a real time basis.
Finally,in respect to the above,incase you are selling your car or its written off,they are still the same people to extract the gadget for you from the 'secret' location,at a fee.
I approached one of the providers/sellers armed with the above information. Told them to sell the gadget to me so that I can have my trusted mechanic hide it in the car for me,and they declined. If there is no fishy business here,they could have accepted.
Caution:
Since they are the ones programming the device for you,they never answered me this question: ' How sure am I that you people you will not on a later date come tracking down the simcard you put in the gadget,locate my car and whisk it away?'
Ask the question and see if you'll get a practical answer.
Hope I've made sense
