(More customer reviews)Update 16/11/2009: Died in October 2009 for no apparent reason. Luckily enough I got it replaced and will give it a second chance, the new one is working as of November 2009 and I will update the review if anything unaccepted happens.
Update 18/07/2010: Replacement still gong strong (knock on wood)
A products that does exactly what its supposed to do. :)
I have had it (2-3 months ago), and couldn't be happier.
Reasons behind the purchase:
-----------------------------
- I didn't get it to deter any theft attempt, we all know that if any needs to get into a car, he will be in, out and away before the $5xx viper draws enough attention.
- Any ways, the reason I bought this was because of a couple "hit and run" I had during the past year, lousy drivers denting/scratching the side of my parked car at the grocery parking lots and just leaves. I installed this for the hope that it draws someones attention just enough to get the plates of the offender.
Bang for buck:
---------------
Even the most basic installation for a conventional alarm, that's without hocking up the windows, power locks or installing a hood/trunk sensor would cost at 2-3 times the price of this unit.
If you don't want the car to be driven away, then an immobilizer is the way to go, again costs so much to install. although same company has a brilliant idea about remotely activated starter relay. Master Lock Starter Sentry Vehicle Anti-Theft System
Oh, not to mention the $4 yearly discount on vehicle insurance. ;)
Security:
----------
And for those asking "if someone has broken into your car, what's to stop them from unplugging the sensor and throwing it out the window? Or popping the hood and ripping the alarm away from the battery?"
Here is what I think:
- Once triggered the siren wouldn't stop without the fob unit unless disconnected from the battery.
- This alarm should be triggered by any voltage drop as well.
- Can't we make the same "rip the alarm away from the battery" about any other more pricier alarms ?
Convenience:
-------------
If you know the way around your car (that how to connect/disconnect your battery wires) it would take around 10-15 minutes. If its your first time under the hood, I would give it a 30-45 minutes max.
Setting Sensitivity:
---------------------
One more issue is how to set the sensitivity, there is a useless side screw on the sensor, forget about it. The proper method is posted on masterlock's website.
Taking the test:
----------------
I have a Camry'99, which I can claim a bigger than typical car, sensor in the cabin is a pressure sensor, it highly depends on how big is your car. By default it didn't fully work for my Camry (just banging the front doors used to trigger it), after fob sensitivity setting opening my trunk would trigger it.
At highest sensitivity setting, I can't even get it to arm if its raining, because the sensor senses the droplets on the body of the car (tells you about how sensitive it is), medium sensitivity should work no problem.
Cons:
------
Why is it losing a star ? first documentation is as good as non existing, especially on how to set the sensitivity. Second, this would be perfect is it was 2 way (fob beeps to let you know alarm was triggered).
Final thoughts:
----------------
This is a variable sensitivity, cabin pressure sensor that lives to the promise. Better know what to expect rather than getting disappointed.
