  • Works
Size: CW-8131
This alarm is easy to install and easy to use. You can set the sensitivity with the remote control, and if anyone makes any contact with my car it sounds four times, a warning, then if they mess with my car again the alarm goes off and makes very loud noise that can be heard far away and it lasts about one half minute or so. It makes one beep when you turn it on and two beeps when you turn it off. Very good until, would recommend. ... show more

I liked that it was cheap. But I guess you get what you pay for alarm. Stop working after a month. So I just got a replacement from the company. Thank you for standing behind your product. I will install new alarm this weekend

  • EASY install you save couple hunds$ dyi!$
Size: CW-8131
Had to jump here and write review because I truly love the ease of install, the very loud alarm 🤠 and great price. Its basically positive red wire and negative black wire that goes right to the battery heads, just loosen the terminals a little and slide the metal pin between and retughten, easy peasy! My van is an old Ford E250 with very tight under the hood small area so i couldn't find a close by metal piece to screw the metal mount unto, i made do with attaching a couple of zip ties and Away she goes, thank God 🙏 this unit saved me paying someone who would otherwise have connected the milkion wires off my other viper alarm and God knows what shorts and other problems that would have maybe ensued . This is a genius piece of solution this alarm 🤠 Zhank ya Berry much 👍 ... show more

  • Great but Not!
Size: CW-8110
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. ... show more

  • WORTH IT
Size: CW-8182
Please note that this is a mild car security system. It comforts the car owner, who needs to let people know there is some form of protection. The sensitivity is a problem. In my case, I have a 1987 Monte Carlo, and I don't want any wires cut to install a better alarm system. Additionally, if you park your car in your backyard and take it out occasionally, this will work for you. I would not recommend this for a high-end vehicle with a daily driver. It's a good buy. ... show more
