Ok...here is the info you need. Lojack is installed by trained and certified personnel only, they all have to go through background checks that are very strict to be able to work with the product. Also, you are told not to tell anyone you have it, keep any papers with the bike that say you have lojcak and there is no markings on the unit to distinguish it from any other OEM part. Also the unit has a battery on it that is charged and used if the unit is ever disconnected from the bike. Think about it, if someone is dismantling your bike, all of the parts will still be in the same area that the rest of the bike is and the criminals. Our rep just came in the other day to help install one of the new systems on a bike and i asked him what the recovery rate is in Ohio. Since the system came out the, every (100%) of the bikes stolen with lojack were recovered. Including a major bust in Lockbourne OH that recovered 24 or so bike along with tons of other stolen equipment, all because one bike had lojack. More proof yet that the system works and is worth it is that our Chicago store has had somewhere around 160 bikes now that have been stolen (customer bikes). All of them have also been returned. Also, if your biks is not found within 24-hours, you get the cost of the system back. If there are any other questions let me know
