Serves its purpose.

Easy install. Left all the functions as factory installed. Had a very windy day and it went off once. That was fine. I can always reduce the sensitivity. I had a catalytic converter stolen 2 months ago, so I got this as a deterrent.

Fast Guard Alarms, This is a wonderful product. Good price and Very easy to install.

Thank you Javier, we appreciate it. Lando

Great Theft Deterrent

Very sensitive. Easy to install. Good price. Could be a little bit louder…can’t really hear it when I’m in my back bedroom…but certainly loud enough for the thief to hear it!

Thank you for your feedback, Robert. Yes, despite our alarm being loud, the sound level does reduce a bit once under the vehicle, but rest assured, the thief will hear it well.

Gary Schleicher

Very easy to install. Hopefully it won't be needed, but it's a piece of mind. Maybe the thieves will let me alone and move on
