    I had the system installed at best buy and i was satisfied from day one. the system was great, the alarm was annoying which is what i wanted, and the 2 way remote is such a great addition to the remote. with fully adjustable sensor sensitivity you can't go wrong with this alarm. I suggest you double this up with the Proximity sensor which i use and its AMAZING. if anyone takes a single step in my vehicles direction it sends warning chirps and then goes off if they remain in the area. coming from a guy who had a break in AND had his rims and wheels stolen, I am telling you this has given me the ability to sleep at night and wake up as soon as anyone goes near my car after hours.

    This alarm is worth the cost. The remote clearly states if the alarm has given a warning or is actively going off, so it's great if you're at a restaurant or in the office and nervous about your car.

    I began researching aftermarket car alarms, due to an increase of car break-ins in my area. I came upon the Viper series of car alarms and have been aware of the name for many years. For me, I believe security relies heavily on deterrence and the name was definitely appealing considering my previous knowledge of Viper. I had the car alarm professional installed by a Best Buy Car/Audio Technician. I love the ability to add other features; such as remote car starter and also the ability to increase the sensitivity of the shock sensor. I have had the alarm or about a month and have not had any issues, so far. I also appreciate the feature that allows me to see whether the car had been disturbed while I was away and the ability to be notified via remote of an intrusions, as long as I am 1/2 mile from my vehicle.

    I have one of the most stolen trucks in the Bay Area. My truck is always where I parked it, must be a good alarm. I like the fact that it chirps the remote when someone activates the alarm, up to a mile away

    This is a great option if your vehicle doesn’t have factory installed alarm system. This is a great product that notifies you on the remote if the alarm went off while you were away. Overall great product!

    If you catch this on sale then you would probably would want to get it. It doubles as a remote start great for winters and also a car alarm. Only one issue and its a big one. Too take advantage of the free install which is recommended you will have to schedule at another BestBuy out of town because our local one does not have any techs currently doing any mobile installs.

    I absolutely love my new remote start system on my car. I pretty much use it every single day. Especially now that it's hotter in California. I just set my AC before I get out of the car and remote started from my house in the morning so by the time I get into the car it's already cool down.
