So far so good

After 2 cats being stolen in under a year, I purchased this alarm. A couple mechanics recommended an alarm over any shield or cage because they had seen them cut off. It was easy to install if you feel comfortable to jack your car up. It triggers immediately with the first pump of a car jack with a loud single beep (with the alarm to follow a few seconds later). I originally wished it would immediately go into the full alarm instead of the warning beep. However, after using this for several weeks, I'm so glad it does not. This has given me the extra few seconds to hit the disarm button once I either open or close the car door but have forgotten to turn the alarm off. With a key fob that unlocks my car when I approach, it is very easy to forget to to turn the alarm off before you get to the car. I have yet to set the full alarm off myself but I have a very small purse so I find the keys very quickly after I hear the warning beep.
I'm not sure if this will really prevent thief because people are scum. Between the alarm and the clear warning sticker for the window, I tried at least. This sticker is better than the sticker for the registration I added which just says the company name and no reference to catalytic converters. Now I have the two stickers stacked on both the driver and passage window, so that helps. I'll still keep full coverage on my Priuses for life though.

It works.

So far so good! It seems to be an effective deterrant.

Great Little Gadget

It does what it is intended to do. Instruction was easy to follow, video on website was informative, instillation was straight forward. My only question which was NOT covered is can and how to replace the battery in the remote key fob itself.
