Clifford Matrix 50.5X

Excellent Product, but only one remote supplied, additional remote is expensive. Battery for remote is easy to find (type AAA) and usually lasts about a month with moderate usage.

Installation is a real PAIN so I would recommend a very good friend who is an automotive electrician or be ready to shell out a fair amount of dough for a professional.... But trust me, you can damage your car if you don't know EXACTLY what you are doing when you install.

I was going to get the viper 5900 but it was back ordered so I ordered this alarm instead. Im sure glad the viper was back ordered :)

This is the same alarm system as the 5900 except it comes with a cool carbon fiber covered remote and the viper has a cheesy blue remote. Otherwise they are identical. The alarm works great. Includes a shock sensor for when people mess with your ride and the install was very easy. I haven't tried long range testing with it but I was able to receive signals from my truck from anywhere inside walmart while shopping which surprised me since the cellphone doesn't work inside there much.

Excellent alarm, thanks again sonic electronix for a wonderful shopping experience!!!

If you are looking for a straight forward no-nonsense remote auto start, then this is the one for you. while it is not feature rich with a lot of bells and whistles, it is VERY reliable. If properly installed you will never have any problems with this unit. the range on the remote is about 1000 feet in the areas i use it in. I was expecting more. but then there are few time I am more than that away from my car. And most likely it is an antenna location issue and not a unit or remote issue. The price on this unit is unreal too.
