i had an alarm similar to the one pictured, and i think my brother has the exact one in the pic. neither one of us have had problems with them, i had one on an 02 ram, and he has one on an 06 silverado. only complaint is, the distance with the paging keychain is shorter then the other "basic" remote. other then that, when your in a store, or restaurant and it goes off, you know to go check it out, plus ours could/can tell you if it was broken into, or just bumped. i work about a block from where i parked my truck, and it would start with the 2 way remote, but you would not get a confirmation every time. just one piece of advice, have it installed at a reputable shop, there are a bunch of wires, and some cars/trucks have to have resistors put into the wiring. when somthing goes haywire, your better off having a reputable shop that will be there a year after the sale to fix the problem. i know dodge had a recall that afected the wiring,and i took it back and they just jumped the power source across. but lo and behold the shop closed up and re opened with a new name about 6 mos. later.
