Lock/Alarm works great. Pleased with my purchase.
Received the Motorcycle Lock/Alarm within 2 days as order stated. Product works great and seems to be of good quality. Loudness of alarm is good and works as a good deterent as security. Good price compared to other models that are over priced. Good product for the money

Peace Of Mind
This motorcycle alarm disc brake lock is an absolute must-have for any rider! It’s solid, heavy-duty, and gives me total peace of mind when I park my bike anywhere. The metal construction feels strong and durable, and it fits perfectly on my brake rotor without any hassle. The alarm is loud—seriously loud—which is exactly what you want to scare off anyone messing with your bike. It’s super easy to use: just lock it on, and it automatically arms itself. I’ve used it in all kinds of weather, and it’s held up perfectly. For the price and the protection, you just can’t beat it. Highly recommend this lock to every motorcycle owner who wants that extra layer of security and peace of mind!

Definitely worth the price.
my 2019 Harley Davidson St. glide has a security system already but sometimes we park our bikes and some not so great places to sensitivity is good. The quality seems great easy to install. I love the color matches my bike for the price, very great value and quality I cannot complain. The lock quality seems well.

Sensitive alarm
It works good with the sensitive motion part but sometimes it beeps out of nowhere and the alarm sounded as well. But over all it's a good bike lock .

Money Well Spent
Best money spent on Amazon… rode my bike 18,000 miles over 10 weeks to all four corners of the United States and this little alarm gave me peace of mind everywhere I went! Easy to use and very sensitive once activated. Can’t even get into my saddle bags without it going off once I’ve set it — which is exactly what I was looking for. 🚨💪🏻

Not bad for the price
The alarm is not verry loud. Seems would not deter a thief but guess it is better then nothing
