  • AMAZING LIGHT!!;
This brake light/alarm is the best I've ever bought. Multitude of light settings, and a deafening LOUD alarm. The light stays on steady while moving, but at a standstill it flashes and is quite the attention grabber. The remote controls everything and when the alarm is set even the smallest vibration will set it off with a warning sound. Once moved the alarm is fully triggered and you'll hear it on the other side of the store! Charges fast, and holds a charge for quite a while. This light is worth every cent, loud, easy to set up and a great alarm to deter theft. ... show more

  • It works!
Model: SF32 Alarm one pack
Had this for 11 months and it still works great. It’s loud and gets rid of the thieves looking to steal. I had 3 bikes stolen in 5 months. Yes they were chained and locked. Now, they just touch the bike and this alarm starts screaming!

  • Great product
Love this product I installed it on my golf cart and it works great as a horn and alert you when somebody sits on your golf cart

  • Use on a chain link gate
Model: SF32 Alarm one pack
Like the vibration sensor. Makes a sound if the gate is touched. What I dislike is it works most of the time and other times it does not work. Charge the unit every week with a portable charger. Overall it is a great unit and it is small enough that it is barely visible on a black chain ling gate.

  • Works well for my purpose
Model: SF32 Alarm one pack
I bought this alarm to use as a deterrent for the squirrels who raid my bird feeder. Although it is not intended to go off automatically, it emits a loud sound when the remote buttons are pressed. I attached it to the railing around my deck, under the bird feeder, so it's close enough to give the pesky squirrels a jolt of noise. I like that there is a variety of alarm sounds, which helps the squirrels not get accustomed to the noise. Excuse the dirt on the railing and the alarm in the attached pictures. The alarm has been in place for many months and has collected dust from the weather, which doesn't affect the performance at all. ... show more

  • NOT WATERPROOF
Model: SF32 Alarm one pack
I’m on my second unit and still getting water in it for some apparent reason. I ride my motorcycle in the rain. Or I can be somewhere and it starts to rain, where is the protection of I have to take the alarm off every time it rains. Not a happy camper.
