    • This thing is LOUD and very Sensitive!!!!
The media could not be loaded. I was a little skeptical about ordering this Alarm being that it is inexpensive. But after ten minutes of installing it with zip ties under the seat of my very expensive folding travel scooter all doubt was replaced with true joy! This alarm works fantastic, the remote transmits from a LONG distance and the alarm sound is incredibly LOUD, and very sensitive on the highest sensitivity setting. (see my video) You can turn down the sensitivity setting, it has settings between 1-7 for sensitivity. I also was happy to find that the alarm was very consistant. I armed it 10 times and then "wiggled" and bumped the scooter and each time the alarm triggered. This alarm will give me piece of mind when I leave my scooter unattended, like on a sidewalk outside a shop or store that I cannot get into while riding it. Before I always had to keep an eye out for the scooter and worried someone would take it. (It weighs less than 50 lbs.) The only negative is that the zip ties included are "brittle" and one broke when tightening it, so I chose to use better quality ones that I had in the garage. It is so refreshing to find a product that "does what is say it does." especially since it is inexpensive and made in China. ... show more

    • For the money it is loud and easy to use
it needs to be used unenclosed, outside whatever it is protecting. if it is touched it makes a hell of a racket. Stick one on your laptop, if you like to leave it on the table when you go to the barista for a refill. Put one on your bike when you park it outside by the door. It goes off briefly if the item is touched, and non stop if it is touched again. You turn it on or off with a remote. All it does is make a racket and you have to be there to hear it and react to the disturbance. For the money it is somewhat useful. But if your item gets carried off while bleating it's head off at 120 DbA, you're out of luck. if you put a lojack on it also, located someplace not obvious, that might be a great way to trace it and retrieve it if the thief stops looking for alarm components after removing the noisy one. ... show more

    • No, not "super loud"
Works as described but not super loud. If placed under a motorcycle seat or under the tank, it's audible but range is shorter than desired, ~100ft before it becomes background noise.

    • 1- Easy to install, 2- remote control, 3- sensitivity control.
I installed the alarm inside a two wheeled tow behind trailer to protect against theft. I turn the alarm off when I will add to it and when getting ready to tow it. Otherwise the alarm is on and I set the alarm sensitivity so that it will only sound off if the trailer is being hitched up to a vehicle, or jostled around by hand. If a local bear or raccoon moves it around enough it will also alarm, and I can remotely disable the alarm and reset it when the animals have departed. A very good item in my opinion. ... show more

    • Works great for the price
I bought this to hopefully deter someone from stealing the catalytic converter from my prius. I put it under the hood so the sound will be piercing, but in a place where the thief wouldn't be able to find it. Pros: it's very loud and cheap. Cons: It's very sensitive and gets set off almost every time a trash truck drives by. I'm sure it annoys my neighbors when it goes off, but I don't care. I mainly have it to deter someone who doesn't want an alarm blaring at 3am while they are up to no good. ... show more
