Kryptonite Keeper 785 Bike Chain Lock, 2.8 Feet Long Heavy Duty Anti-Theft Bicycle Chain Lock with Keys for Bike, Motorcycle, Scooter, Bicycle, Door, Gate, Fence

Unbeatable lock very sturdy and easy to use the length is perfect to secure your bike anywhere it us rust resistant and waterproof

It's pretty good, does the job and there are no mechanical problems, no rusting and no seizing up so far.

I have every confidence in this lock. I would imagine there aren't many people around regular walks of life who could breach this lock. Its exactly what I was expecting.

It's fantastic

Very good quality bike lock. Heavy duty and secure. Easy to use and protection from scratching and damage to bike. Would definitely purchase again.

I've been using this for a week now and it's a good lock. It is a bit heavy but helps weight down your cycle anyways.

Fantastic lock very strong lock definitely recommended

Solid and chunky, good for this price point. Have been using for 3 months with no issues. However just recently I've noticed the lock becoming reluctant to open. I've applied grease to the mechanism which seems to help a little, but probably 3 in 10 times, the lock will rotate but not disengage, requiring considerable force and several attempts to get it to open. Less than ideal when fumbling around in the dark on a rainy morning.
