## 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!
