Review: It cheap and it works! What more do you need to know? - A group of cockroaches tried to steal my bike and because of this cheap $20 thingy it was left. They actually broke the ignition cylinder and turned on the bike. As you can see in the pictures they hammered away and couldn’t get it off. This strong sensitive alarm is worth more than this. Comes with a storage pouch that can be used while mobile, It’s easy to install, and secured my boobie! It has a loud and super sensitive alarm (which can be annoying on rainy and or windy days). It worked for me. Definitely getting another. Thank you!!!!
Review: Great for disc brakes - Great product for anyone that has disc brakes on their bike or motorcycle. Not only will it slow down a thief or stop them but it also has an alarm on it to draw attention. The alarm is very loud and very annoying. The alarm is very sensitive. It gives a little warning beep and then goes completely off so doesn't just go off immediately if somebody bumps into it. It fits perfect on my electric bike. Easy to use

## Questions & Answers

**Q: Is this Worth spending my money**
A: I'm sorry but it is not worth! If this product is purchased for "mechanical" anti-theft (disc lock), then I do not recommend it!
Lightweight and not very durable. In my opinion, the black part is empty because it houses the sound part and the battery compartment. The only positive note is the sound part .. the sound is very loud!

**Q: How to replace the battery of this alarm disc lock?**
A: 1. Open the bottom 4 screws and open the cover 2. Take out the battery compartment and remove the old battery 3. Insert a new battery, paying attention to "+" and "-" 4. Replace the battery compartment, close the cover, and secure it with screws again to complete the task

**Q: I would like to know what the diameter of the pillar of this motorcycle lock is. Is the diameter the same for different colors?**
A: I guess you want to know this size. The diameter of the lock pillar is 0.25 inch, I think this is in line with almost 99% of motorcycle disc brakes unless your disc brakes have no holes.

**Q: Can this be used in rainy days?**
A: It is not waterproof, the lock cylinder became rusty after using in a rainy day, the worest is I used it on my bike and it can not be opened with the key! I have to find a locksmith to open it. The cost is much expensive than the lock itself. BAD EXPERIENCE!
