bSafeMobile drive app works. Not as "intrusive" as I expected. It too two weeks for Amazon to get me the device which was $159 that included shipping. The installation of the actual device took 5 seconds and 30 seconds to sink to the blue tooth in my cell phone. I drive a 2002 Suburban. The app took 1 minute to down load. It took me quite awhile to locate the "access" code which was in my "spam" email folder. As to the operation it is pretty good. It does not work immediately when you get into the car and takes about 2 - 3 minutes. Every cell phone in the car would need to be connected to the device via blue tooth to prevent others in the vehicle from their personal use. After that if you (Driver with app on their cell phone) try to text, email or call it flashes how it is unsafe to text and drive and not allow you to text. It can be over ridden in an emergency, a passenger could over ride the application or anyone could unplug the device and stop the blue tooth from sending out the signal. For me it works and it will keep me from getting a ticket or worse, causing an accident. The product works, it probably can be installed in a more permanent position or if made part of the car itself actually stop the loop holes. It is for real folks, I can see the teen drivers hating the bSafeMobile for sure. Concludes report, all is good wit this life saving doodad.
