Review: Fantastic! - Great lock for the price. I purchased it for my Ninja 500 and it fits perfectly on the brake rotor without any issues. The lock feels solid and well-made, and the alarm is much louder than I expected. One of the things I was most concerned about was whether I would actually hear the alarm if someone tampered with the bike. I live on the third floor of an apartment building, and I can easily hear it from my apartment. That alone gives me a lot more peace of mind when the bike is parked outside. Setup was simple, the fit was perfect, and the alarm is definitely attention-grabbing. Highly recommend for anyone looking for an extra layer of security for their motorcycle.
Review: Great security and peace of mind - Solid build quality and the 110 dB alarm is very loud—definitely a strong deterrent! The bright reminder cable is a great touch so you don't forget it's attached. Easy to set up and works great

### ⭐⭐⭐⭐⭐ Eh… good price.
*by P***S on July 6, 2026*

They work, great price, fits well to almost any bike but once it rains a few times and water gets inside it’s a matter of time before it shorts out and dies. Comes with extra batteries it doesn’t matter since it’s not water proof. If you’re using them in dry places you’ll be good. It’s loud enough that it wakes me up anytime it goes off and I live on the 5th floor.
