I Know a great deal about them.
#1 Black WIDOW SUCKS!!! aviod at all cost
#2 Autopage is OK but still not DEI or compustart Quality.
Get a DEI unit! Responder like the viper ahh [censored] umm 790xv or somethign like that or the CLifford RS2.5X. WIth a battery backup, and a Prox sensor. The battery back up will make the unit still work for 30 mins if they kill the power to it and the prox sensor is like radar and anything moving around the car it will send a warning chirp if to close then full activation will happen.
The DEI's are two way up to a mile in perfect conditions more like 1/4mile in every day stuff. One of the Vipers can be GPS tracked and you can call to remote start your car if your out of range.
Black widow like 10 feet if it even works seriously its a peice o sheeeeeeeeeeet!
Autopage as i stated is average i would give about 7 out of 10.
DEI products in the RS/Alarm field are far superior in cost and quality than almost any other brand. So Clifford, Viper, Hornet, Avital, Rattler and Valet or any Directed Electronics INC alarm
Compustart is cool but very expensive in my dealings with them.
