Mengshen Wireless Vibration Alarm, Anti-theft Burglar Alarm for Bicycle/Bike/Motorcycle/Car/Vehicles/Door/Window, 110db Super Loud (Remote Control Included)

Easy to install works a treat would have liked it to be waterproof but still a good piece of kit

Cheap and appears to work well. Easy fix to back of my shed door. Worth the money and remote great

It is a great item. Only issue is i use it on motorbike and its like a sticker, so not sure how would be it on rain or will it fall during a ride and also it would be easy to turn off or take bateries out if left visible, so i put it under the seat so its locked, it works great but just seat covers sound a lot, so if im near i will hear someone trying to steal it, but if im far or sleeping its not loud enough to make me wake up or do any proper noise to make other people to turn around. Again its loud and good if its not covered like in my scenario. So overall good quality iteam does the job.Btw so far just saw few kids trying to sit on it or just look at bike so it started and they moved straight away, so it sould be enough to make people dont mess around it.Btw it would be great if company do oposite of alarm like notifier so bike doesnt scream when someone touching it, more like alarming me buzzing in my pocket or makins sound to my phone or keys or something so i can go and do something about it even if i sleep, bike buzzing might scare them away but peoples attention not gonna help much.Great product anyway.

Someone attempted to open my car door one night and it wasn’t until in noticed it on the camera the next day, that I knew it happened.I put the alarm in my door well and it’s really sensitive but it’s exactly what I wanted. I park on the road outside the house so even just the neighbour closing their door with force sets it off for a few seconds…it goes off but then it’ll alert again.Only lasts a few seconds and it’s loud enough it wakes me up of a night if a cat goes near my car.Again it goes off after a few seconds but it’s loud enough to alert you and certainly scare off anyone attempting to break into your car.Also had an issue with rats getting into the engine and since I’ve had this fitted I’ve thankfully not had any instances (*touch wood).Happy with this for the price as doesn’t involve any hardwiring.Had the same batteries in it now for a few weeks and it’s still going strong

This is a handy gadget to have but there are serious draw backs. First, if you are using this in your car, please note the alarm will more than likely not go off if a would be theif accesses your car from any door other than the one you have attached the alarm to. So if you have it in the driver side door well, opening the passenger door will not set it off. If you have it on your dash than no doors opening will set it off. Second, should they picked "the right door", the alarm will only initially sound for about 3 seconds then turn off. If the theif runs and leaves your door open. They could then return and continue to ransack your car (unless you heard it and came running). If they close your door in their panic, the alarm may continue to sound but it is then so muffled that no one would be able to hear it. So again, unless you heard the initial 3 seconds with the door open, you're outta luck. I'd say this alarm would work best inside the home.

If they get in they will hear the sounder for days

Stopped working after a month
