The new 1-mile range Matrix 50.5X Responder SST System from Clifford is the most advanced 2-Way Security and Remote Start system in the world! The new Matrix 50.5X employs Spread Spectrum Technology, digital frequency hopping and multiple frequency transmission to assure that even if a frequency is blocked, the signal still will go through. The Responder SST also has dual error correction systems to combat signal data corruption and minimize any signal interference. The end result is an amazing range of up to one full mile!

The interactive display on the Responder 2-way remote confirms all commands (almost instantly) with simple to comprehend icons and text. The remote alerts users to security system triggers by beeping or vibrating when out of audible range of the siren. The Matrix 50.5X will also start your vehicle with the push of a button (when remote start is installed), and you'll get confirmation back that the vehicle has been started.

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.

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.

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!!!
