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

Delivery next day great, you will need batteries for main alarm AAA's most people have knocking around at home. 2 adhesive stickers for back of alarm 1 at the top & 1 at the bottom just peel off & stick where ever you want it , remote self explanatory by symbols on front similar to car's, easy to set alarm and very sensitive but can be altered if need be , loud too , easy to stop & their is a panic button on remote to set off alarm if you want to ! Very pleased with mine placed on inside of entry door to my camper trailer conversion and it's never gone off on its own even in windy weather but if I go to open door with handle it sets off so does exactly what you want it to do VERY PLEASED WITH IT ! Would buy again definitely! even for other uses around the home inside not just for sheds or trailer's.

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.

Wanted a separate alarm for a couple doors of the house & with the remote control feature, this seemed ideal. Very easy to instal (all of 5secs max), simple to add additional remotes, good sensitivity setting & VERY loud...! The one negative I have to say is when disarming, it gives off loud "beeps" so was not suitable for one intended position (would've disturbed babies) but since this is designed primarily for vehicle use, or maybe back doors etc, I can't gripe much. Overall very good bit of kit & in use. Will be purchasing another unit for garage too.

It does what it needs to. Pleased with the product and price.

Great but just not loud enought to hear out side the car. But worth it if in a place you can hear it . Still works and would be better suited if I was to use on a bike possibly

I've bought about 5 of these now, and also given a couple to friends. They're sold as shed alarms which activate on movement. However I use them as alarms to scare big birds like magpies and starlings off the several feeding stations around my property. I deactivate the movement feature, and just use the alarm function on the remote device from the comfort of my kitchen or bedroom. I have 6 CCTV cameras, so I can see when the large birds arrive. They hate it, but other little birds, and even woodpeckers aren't bothered by the very loud alarm. I cover the alarms with a piece of waterproof fabric, and attach them to feeding poles with cable ties. Pic shows one pole with two alarms attached. Easy to install, long battery life even in winter weather, and a good price. The ones in the pic are at least 60ft from the kitchen where the remote is used, and has no problem, even going through the walls.

Way too quiet.. The whole point of this is that it's an alarm if someone tries to steal your bike or your car or whatever but the reality is it's so quiet no one's even going to notice defeats the whole purpose..

Simple to use and loud! All good.

Of course it doesn't compare to a build in car alarm, but its a great cheap option for extra security. Works perfect, but the alarm sound isn't that loud from inside the car. Enough for me though, as my car is parked in front of my apartment.

Alarm works really well. Super easy to arm/disarm with the included remote. I put one on the inside of the garage roller door in case of jemmying. Can arm/disarm from the outside through the metal roller door! Only downside to this alarm is that the battery door doesn’t have a screw in it to stop it being quickly opened and batteries removed if alarm goes off. But easy fix is to wrap some tape around alarm to make it difficult to open in a hurry. All up, very impressed! Would highly recommend. And battery life seems to be great but have only been using it for a few days so can’t really comment yet. Super loud for it’s size too.

I had to find a reasonable car alarm for my Ford Escape. This alarm has a loud siren and works whenever a leaf, anything touch this car. the price was only 15.00 which I was skeptical at first but it uses only 2 AAA batteries and I'm telling you, this alarm is loud and very clear. when you open the car door, the alarm shrills loud until you push the alarm to cut off. your ears cant handle this loud noise. My car is sensitive when its brushed against or even when the wind blows hard ! I feel secure now that the neighbors can see and hear my alarm is set

Perffekt !

I bought two for my old car. I like the bright red blinking light. I placed one on each front corner window (I have an old car some people couldn't help ransack in the past). Since installing these, not one single attempt to break into my car on this quiet street. I know because I have cameras aimed at the car as well. They just walk on by. One odd thing to remember is that if you find that the alarm keeps arming itself when you try to remotely shut it off, it's because the alarm batteries need replacing.( I initially thought I had a problem but that's all it was). The alarm is loud enough for the job. For the price and functionality, I would buy again without hesitation. Update, on reviewing my security camera aimed at my car, I was able to see someone purposely tap my car, causing the two alarms to go off and the potential thief to move on. That's a five star result. Also, if you find these alarms blinking away, even after receiving confirmation that they are turned off, it's a sign the two AAA's are due to be replaced.
