Master Lock 8143D Combination Bike Lock, 4 ft Long, Black

My bike was stolen the first day I used this lock. Looked like it was effortless for them.

This lock lasted less than a week before my bike was stolen. The thief broke the lock at the "key" insert. From the fracture, it's easy to see that the material used was very brittle. Save your bike and time. Get a meaty u-lock. My bike was not worth much so I took a chance and now I feel like a fool.

Had it in my jeep keeping my emergency box secure. Lasted for a little over a year and then it fell apart. Noticed the cable pulled out of locking mechanism. I'm glad I didn't use to to lock up my bike.

Terrible lock for the "Baleaf Oxford Fabric Waterproof Bicycle Cover for 2 Bikes Lockhole Design". Someone stole my cover by breaking the lock. They did this by pulling the wire out of the lock block.

I was using this to secure my bike on my front porch, and literally within a 10 minute window someone came up and cut this lock and stole my husband's brand new bike. I am not a happy camper. NO I do NOT recommend this. I live in what I felt to be a generally safe neighborhood and yet a thief cut through this like it was child's play. The police officer that came said it looked like they cut it with just a knife, which was rare. Yet shows how cheap the cable lock is!

Going with the Master Lock brand I thought it'd be a solid build. It was cheap, but I didn't expect it to be cheaply constructed. It all works as intended, it's just not very sturdy. One of the locks fell apart when my kid dropped it off his handlebars. The number wheels literally fell off. I didn't try yanking it apart when it was locked but it made me less trusting that it'd stand a good tug if someone wanted the bike.I'd recommend you spend a few extra dollars for something sturdier.-- This is how I rate my purchases --5 Stars: Product works exactly as advertised, is a good value at the price point purchased, and I would buy it again or recommend to a friend.4 Stars: Product works exactly as advertised, fit/finish are what you'd expect when purchasing this type of product, but the product may leave more to be desired.3 Stars: Product generally works but it may not be a good value at the price point or may need some improvement. I probably wouldn't buy it again.2 Stars: Product barely works but can be made useful if you try. I would not recommend for purchase.1 Star : Product does not perform as intended and in my opinion is probably a waste of money.That's my review scale. I also want to point out that if I receive a product that I would give three stars or below to I usually contact the vendor and let them know the problem. The vast majority of the time they are willing to replace or refund my purchase. This is why you'll see very few three or under review from me. I hope that is of some help to everyone!If this review was helpful I would love it if you could reply YES to the question below "Was this review helpful to you?" Thanks so much!

This is an economic but durable solution for situation when you want to lock your bike in a public place. The section of the cable is by no means thick enough to deter anyone who really wants your bike. I would not let my bike with this lock overnight in critical areas, but this lock is fantastic when you stroll downtown and stop for a coffee or lunch somewhere. It comes with a fix combination, meaning you cannot set a more memorable one for yourself. Make sure you mark the four digits down somewhere (phone, maybe?) so you do not look like an idiot trying to steal your own bike!

This lock always was “sticky” and jammed constantly. Not the situation you want to be in on a cold night trying to unlock your bike in a sketchy hood to go home. I always wondered if it was me, or if I inadvertently re set it but then at the last minute would unlock! After a min. of 10-15 minutes. Finally it did not after two people tried & I had to cut the cable clean off with my Dremel, (plastic cutting disc and metal cutting disc) which I was just lucky enough to have nearby. Every time this jammed on me, it was always a bad time for it to happen. Also I have to physically wrestle with the too strong cable which never relaxed, always strangling my bike and stressing me out.This is really a 5 star review for the Dremel!
