There is also a thread on attynorby's feedback on TxtAlert. I want to reiterate that I do not have any proprietary interest, or being paid to post this message.

Let me also make the claim that there is no perfect anti-carnapping/carjacking device . TxtAlert is intended not to be the perfect anti-carnapping/carjacking device, but give us a way to fight it out with would-be carjackers and carnappers, at least, to give you time to delay the possiblity of them running away with your vehicle, until the police themselves can arrive to deal with the carjackers (providing they not the criminals themselves). As attynorby has stated, it uses GSM network as a means to arm or disarm an alarm (independent your your built-in system) alert you if your car has been opened or if the engine has been started, and it also gives you a means to immobilize your engine, and lock your car, in case they are outside, and are trying to trouble shot your car. lock your car to deny them access, that is if you already have found a safe place to hide, and have called the police. (Let's hope na when they see the criminals, they will not greet each other na PAKNER!! )

It would be difficult to give more details as I think attynorby has given an excellent review.

Suffice for me to say, that I hope I will not be the first one to try this on an actual situation, but at least, I may have a means to try to hinder them from taking vehicle, without necessarily putting yourself in the forefront. As I said before "beats buying a handgun, and trying to fight it out with carjackers with military or paramilitary training.

Also, I would like to apologize to the members of the police force and military (the honest ones). It is not a means to put you guys down, but maybe just a wake up call to rid the ranks of scalawags.

P.S. There is a perfect anti-carjacking device, one that can have force shields, with photon torpedoes, can teleport you to your place without leaving the car, can fly and can do a warp jump of factor 10 (For Star Trek fans) Let's hope there are no carjacker Klingons here.
