Review on Mengshen Wireless Bicycle Alarm: Anti-Theft Burglar Security Alarm for Bike, Motorcycle, Car, Vehicles, Door, Window - 113db Super Loud & Waterproof (Includes Remote Control) by Steve Brethorst

I was a bit skeptical about ordering this alarm clock because it is cheap. But after ten minutes of installing it on zip ties under the seat of my very expensive foldable touring scooter, all doubts were replaced with true delight! This alarm clock works fantastic, the remote transmits a signal over a LONG distance and the alarm sound is incredibly LOUD and very sensitive at the maximum sensitivity setting. (see my video) You can turn off the sensitivity setting, it has settings from 1 to 7 for sensitivity. I was also glad that the alarm clock was very consistent. I turned it on 10 times and then "wiggled" and hit the scooter and the alarm went off every time. This alarm gives me peace of mind when I leave my scooter unattended, for example on the sidewalk near the store where I can't get into while driving. I used to always have to watch out for the scooter and be afraid that someone would take it away. (It weighs less than 50 pounds.) The only downside is that the included zip ties are "fragile" and one broke when tightening, so I decided to use the better ones I had in my garage. a product that "does what it promises". It's also cheap and made in China.
