Jammed After Two Months
Daniel Pi•April 20, 2018
It was alright for a couple of months, but then the keyhole got jammed, and now it's useless.
Now, I'm not sure if it was the keyhole becoming stripped (although the multiple keys were fine), or if something was lodged inside by nature, a lockpick, or if it was my own doing, but that's that. It won't unlock anymore. Luckily, it wasn't locked to a bike rack when it stopped working.
Other than that, it seemed sturdy, albeit heavy. I would say it decreases the risk of theft, simply because it seems it would require more than a wire cutter to break it.
Also, a minor issue was that one of the small metal pins on the cover broke. I guess you get the quality you pay for.
Now I'm no expert, but I'd chalk it up to low quality parts.

locking mechanism freezes
Alli Jan•March 27, 2018
This lock worked great for three weeks, then the locking mechanism froze up and the key wouldn't turn. Took me about 20 minutes to unlock my bike. I took it home and WD-40'd it to see if that would help, but now it won't open at all. I was hoping all the other reviews were unlocky (haha), but I guess you get what you pay for
A good length for locking my wheel and frame to something
Emily Spivack•March 17, 2018
A good length for locking my wheel and frame to something, but the bolt ensuring the cloth cover kept the chain hidden broke within a few days of use. The worst part was that when it rained, my lock got stuck and I had to use copious amounts of WD40 to unstick it...very inconvenient to say the least. Also, not the worst thing but still irritating, the yellow cover over the keyhole falls off half the time.
Defective Lock
Amazon Customer•March 16, 2018
The key broke off in the lock mechanism while trying to extract the key after unlocking. This happened on just the third use, but the lock mechanism was very difficult to turn and retrieve the key from the get go.
Tough as they Get
mari•March 14, 2018
This was exactly what I was looking for. Actually the picture doesnt do it justice. Its super sturdy and Tough. It will be hard to get through this one. Its kind of heavy, but its great. Worth the price for sure.
