I have been a long time Amazon customer. However, I rarely take the time to review a product. I suppose this is mostly out of laziness or an ambivalent feeling about the products that I purchased. On the other hand I think it's important for me to spend a moment telling you about this portable GPS tracker. This is not the first product I bought from this company and it surely won't be the last. I have an OBD tracking unit in my teenage daughter's car for insurance purposes and to let me know that she is okay. For the record my daughter does know the unit is installed and understands why I have it there. Recently I purchased this portable unit to use while riding my motorcycle. It allows my wife and friends to know where I am in ""real time"" and that I am okay. To me more important than the fact that the units work flawlessly at a very reasonable price for the tracking service they offer is the fact that their customer service is second to none. For the record, I am a pediatrician who employs 33 people in his practice. No one is more aware of the importance of customer service to the success of any business. When the portable device arrived it was not working properly and I knew this immediately because, once again, it wasn't not the first device I had purchased from this company. I called their toll-free phone number and one of the technicians came on the line immediately and stayed on the line, working with me diligently until the unit was working properly. I think their products are fantastic but their customer service is even better. Their products are reasonably priced and they work as advertised. They are always there to help you when needed including nights and weekends. Again, I have absolutely no relationship to this company except for the fact that I have given them money for products that are reasonably priced and work. I give them my highest recommendation and a five-star rating here at Amazon. There is no way you would be disappointed with what they are offering even at a higher price. I hope this review will be of some value to you and I also hope that you will give the company a try. I really don't think you'll be the least bit disappointed.
