Good stuff!

Very loud and effective.

Sharon Wolf
catalytic alarm

I've only had it a little over a week but it seems to be working well. The alarm is loud and is sensitive to movement. It was relatively easy to install, I had to crawl under the car, I'm 65 but it wasn't too hard to do

Catalytic alarm easy Peezy

The install was smooth and easy, even though I had to take it off and re-mount it (my fault). The alarm is definitely loud enough… Accidentally set it off while I was under my truck, scared the snot out of me! LoL The only reason I don’t give it a five star is because of the remote. Wish the remote was a little bit smaller and had a better connection hole for my key ring, it was too tight. Otherwise, really happy with the whole thing!

Good deterrent, good price

Husband installed with no problem. Works exactly as it's supposed to. Nice to have the alarm to discourage catalyc convertor theft. My Accord was a victim a few weeks ago.
