ELECTOP 108dB Car Alarm System, Automobile Vibration Sound & Light Alert

So far so good. I purchased the two pack set to use in my cargo van. I really couldn’t stick it on the dashboard because it’s not magnetized so I placed each one in a pocket near the interior door handle (both doors). They fit and it works perfectly. I tested it out by just grabbing the door handle while inserting the key to open the door and the alarm was immediately triggered. I love this product. Update: Sorry I didn’t realize the magnets were on the back of the device with adhesive. Take the magnets off of the device, peel the paper off exposing the adhesive, stick on your dashboard near the window then lay magnetized alarm device on magnets and voila! Works perfectly! Very happy with the results.

My car had gotten broken into at my daughter’s place and so we had a locking piece that we put on the steering wheel and these alarms inside the car if someone smashed the window or something like they did last time so they are very loud and I like them very much because they protect the car a lot thank you so much

It doesn’t do what it says it does. It’s not sensitive enough to turn on when someone is trying to get in the vehicle. I shook it hard and only got the light to come on, but the alarm doesn’t sound until I actually started my vehicle and it is not loud enough to hear from my bedroom. I don’t think it’s worth it

This is a real option for no wire security alarm. It has led warning lights. It has good sensitivity - I do not have false alarms. It does react to vibration. I put mine on Max sensitivity and a small bump will set the alarm off. I reccomend this car alarm good buy.

Actually pretty loud and sensitive as well. I put them both just under the hood of my van using the included magnets and they work like a charm. Even if just opening the very back door of the van they're sensitive enough to detect it with no problem at all. I'd say they should definitely scare off anyone braking into or vandalising your vehicle.

Not really loud

Excellent

Still working a year later, great for finding your ATV in the bush when hunting

CUANDO LO COLOCAS DENTRO DEL CARRO LA ALARMA NO SE OYE AFUERA

Good deterrent at least for Some jealous and hating people towards your valued car. Making dents and scratches just to satisfy their hatred. Scooter riders can be culprit too when they ride and take swipe at your car. Although works too for ill intentions characters such as theft.

Not loud enough behind closed doors. If the vehicle were to be opened or a window broken it is definitely loud enough to deter a thief, but other wise you wouldn't hear it from inside most buildings or at any sort of lengthy distance. I was pleasantly surprised by how well it picked up vibrations (mounted on the inside of my driver's door). It picked up the vibration when I remotely unlocked my doors, when someone leaned on my bumper causing the car to jostle, when I thumped on the door and when I opened my driver side door. My car is very small though, it may not work as well on larger vehicles. And I was quite pleased with how well the remote worked.
