this is VIPER 790XV 2 WAY

http://clifford.com/products/cp_responder.htm

and this one is Compustar 2WSS - AS

http://www.compustar.org/products/2WSS_features.html

this one supports turbo, and i think it means it has turbo timer ... because i used to have the 2WFM and it has turbo timer and auto cold start engine

which one u choose?

 

viper

 

compustar

 

let say it's the same price of $300 on ebay

 

compustar no question

 

The compustar works from over a mile away! That's cool except if your car is a mile away and someone tries to break in you'll never get there in time . I would go for the compustar - that's my first purchase on my list once I get my car ( after car wax)
