Ideal for those who make a quick trip
Lock is functional, the length was just right for my 35mph e-scooter. The thickness was not that much hardly but it does the job. It comes with a two set of keys.Pros: Great for short trips, ideal for low crime areas but better safe than sorry type of person, easy to lock, affordable, sleek look.Cons: Not for long trips.

Does the job!
Adependable choice for keeping your bike secure. The locking mechanism is straightforward and works smoothly, giving me confidence that my bike is protected. The steel cable feels durable and resistant to cutting, providing a solid deterrent against theft. The length is just right for locking my bike to various fixtures, and the included key adds convenience over combination locks.I’m giving it 4 stars because the key mechanism, while reliable, feels slightly less sturdy than expected. I also noticed that the lock can be a bit finicky to open in cold weather, which might be an issue for some users. Despite these minor issues, this lock provides excellent value and peace of mind for daily bike security.

Great lock
Just make sure you lock your bike with this to a rack or something solid and stationary. Had my bike stolen 4 months ago cause here in NC there are NO bike racks. Had the back tire locked and the drug addict picked up the back and rolled away with it. He ditched the bike BECAUSE the lock is heavy duty and someone else took off with it. You can also get a cable with this lock to be safe.

Good lock, however the mount is poorly designed
The lock is good and durable, but the mount to the bike does not hold it securely. I have to put it in my backpack while riding.
