Basically dude,
from what I have seen on most of these alarms (also missed "repeller" alarms), they are very prone to false alarms, malfunctions and general "shitting themselves",
Cyclops alarms are probably the cheapest and the best for the money that you pay.
I have seen alot of these alarms, where the keypads fall apart from poor workmanship, the actual back-up batteries don't back up, and most of them are wired to work only off the interior light to warn on entry of the car.
Most of these models aren't all black wired making them easy as to check which wire is what and do a trace.
I have seen the sirens on countless Mongoose alarms being damaged by water, where they claim that they are waterproof.
Alot of these alarms also use "microwave" sensors, which will give off constant false alarms from things like a cat walking under the car, or leaving a mobile phone for 5 mins in the centre console.
I make my calls based on my own views of what I have seen.. sorry If I have annoyed someone if you just payed a fortune for the above listed alarms, but I would never own any of the above, even if I had a Gemini.
Brenda im sorry bro but as Alex said and i second it i agree in some cases in most i dont, a mongoose is all black wiring in almost every alarm that they do except the central locking wires are colour coded. no siren is waterproof thats why if you read the instructions they tell you to cover it. now if u leave a mobile phone or a cat walks past the f**ker then just turn down the sensativity of the microwave sensor and shock sensor its that simple....ive been installing mongoose alarms for about 5 years now and ive honestly had one come back and that was the battery in the remote when flat replaced that and its still going strong. and aftermarket car alarms are designed to work for about 5 or so years and then they f**k up as its only small conntacts for the imobiliser and stuff like that....
then again $700 or so to have one supplyed and fitted is not that much when it stops a little 15 year old to steal your car. but if a pro like me wants it then no alarm will stop them, as i chop a faulty alarm espsh the rhinos in 30 seconds flat and i take $100 to do it...
But Brenda i know why u dont like these brands its coz u dont like your car and u want it gone hehbehehehe J/K bro, just some insight into alarms here
*touch wood* my factory brant is working fine...i dont have any problems with it...
yeah touch wood that its working just like mine....
