Easy to install and still works great after a few years since I bought it. Great quality and value for money and no wiring, and provided security. Thanks again.

This is a Good product for a Good price. I had to do online research outside of amazon to understand the difference in models and features. I selected model M810 which is labeled non-destructive installation. It was as simple as attaching 2 wires. The operating instructions seemed lengthy to read but turned out to be very simple to understand. Please note this model is only vibration / motion that triggers the alarm. The remote is also easy to use and has Good Range. Short 1 star as im still trying to find the perfect sensitivity level. A low flying airlplane triggered the alarm so i lowered the sensitivity 1 setting. Thereafter i kinda medium slam the vehicle door and the alarm Didnot go off. Re adjusted to factory settings #4. Alarm triggers at the slightest bit of vibration but altleast it work. This device was installed as a deterrent in my work van. One may have different results with a car. However, Im still satisfied with this device. 👍

I'm unsure --- Definitely a deterred from car thieves or someone who breaks into or messed with your car. A roommate that I don't particularly trust sighs when he heard the alarm. When did you get that?? He asked. Uh huh. The culprit is do believe is disgruntled. Lol. [ It took less than 5 minutes to install fairly basic ] my only concern was draining the battery?? I'll update later if that is an issue. In the meantime --- hahaha. I hope to catch this prick! Thank you.

I am a certified installer and have installed many alarms over the years to Clifford, Crime Stopper, Kenwood, Viper Electronics and DEI. I know DC schematics and car audio very well. I can safely say this system "A" is purely awful. The pros are that is has great remote range, and super easy to install, 2 wires, and it's well made meaning not cheap feeling or material is used. That's about it, all else as in usage and or performance is awful. On every setting for sensitivity, 7-3 the system just goes off every few minutes for absolutely NO reason. I can't tell if it's interference from something around or it's just defective. The system is not sensitive like people are reporting, what is occurring is that it's picking up every frequency around that appears to trigger the alarm falsely. To test this, when I put the sensitivity to 2 or 1 it's stops going off but the issue is that I can jump and kick the car like a criminal and the alarm will NOT go off. Even on 3 it's on the edge of not going off automatically randomly but the protection is non existent. Going with a different system. Won't return it but lesson learned, buy a reputable name and or a product with many more positive reviews.

I am very impressed, easy to install. 2 wires to the battery. You just have to find a good place to mount it. It needs to be mounted to metal to pick up vibration. The default setting was not sensitive enough for me. I set it to 5, opened the door, it did not go off, closed the door it did. I set it to 6, opened the door it went off. I have been vandalized twice since I lived at this apartment. First stole the Honda catalitc converter. Second broke my window. I leave my car unlocked now, let open the door, surprise. AIlive ina second story apartment that has a balcony that overlooks the parking lot. A few months ago the alarm went off, it was kid had my door open looking for something to steal, I yelled at him, he took off running. I bought this August 2024, today is December 16 2025, it still works fine. If you don't have a bunch of money spend, I highly recommend it.
