    Awesome Security System

    This system is great on my car. I didn't have key-less entry to begin with, so this purchase was worth it just for that almost. I am planning on having my car at school so I wanted the extra assurance that it was still okay. The ability for the remote to tell you if someone broke into your car and if the doors are locked is great! The range is well over 1000 ft in open land. However, there are a few minor things that annoyed me. I was going to bring my car back to Best Buy because I was having problems with the car thinking that the trunk was popped when disarming or that the shock sensor had been set off. Luckily these problems fixed themselves randomly, but it was still worrying. Another problem is that I've had is that sometimes when trying to arm/disarm the system, I press the button and it says that the car is out of range. Even though I am standing right next to it. But I know the range is good, because it normally works fine. The only other thing that I don't like is that the siren isn't very loud. If you're right next to it, it is ear-piercing, but if you're inside a house with the car parked at the end of the drive, then it isn't very noticeable. The main point of the alarm is to scare off the thief though so it will definitely do that.

    I purchased this alarm as a replacement for the garbage system that was in already. I really upgraded the stereo with a Nakamichi CD-400 and Focal top of the line Speakers with Phoenix Gold Titanium amps so I really need supreme protection. I did a lot of research and chose the Viper 2 channel for my needs. This system has all the bells and whistles and I love the remote control that shows you on the screen if your door is ajar on just not locked. I love them fact that it will work up to 1500 feet and chirp you if someone is messing with the truck. In the end spend some extra cash because being cheap will cost you. For what I paid it also included installation and a clean installation.

    Ended up going on a different set up to be able to use the original dealer fob. Viper is a good brand but there's no real difference between this model and the cheaper one. You're pretty much paying for the 2 way pager one this one. Range is pretty much the same along with security.

    My car was broken in to so I picked up the Viper. If anything it may be a little too sensitive (it's a good thing) serious thunder can set it off. The range is amazing. The fob works even with commercial ovens and freezers (and cinder block) between it and the alarm

    great product! easy to operate, tons of features/settings. 2-way is really nice to have confirmation on whether your alarm is armed. range is great, and gives peace of mind when armed.
