Packs one hellova 👊🏽

When I read a product review, I tend to wait to make my own judgment on it. Many reviews were stating how loud this alarm is. Well let me tell you, this thing scared the mess out of me . Of course I wanted to test it out after setting it up on the bike but gosh, I really wasn't expecting it to be that loud. This is perfect 😅. Also, the distance this alarm can reach is pretty impressive. Through about 4 walls and I'm still able to set or remove the alarm. Very great investment for any bike. The key is easy to use. There's different alarm sounds to use. I use this in addition to the actual lock I have because those only do so much.

keeps your bike secure

I love this alarm. works great. ease of installation. the directions were simple. It sturdiness is seen by attaching it to a flat clean surface. Keeps my bike secure with this loud security siren.

Big security for small price.

The product works great. (Even when I forget it's on there.) Three-way accelerometer is perfect. Turn it on, and in 2 seconds the position is set. One bump and it gives a warning beep. Touch it again in next 12 seconds and alarm will sound. Great price for security.
