Great lock
Great lock. Great company. Company even sent me additional keys. I did have one problem. There is a clasp for hanging lock to bike. It moved and i could lock device. My bad. I quickly saw that piece was easily movable and everything works well!!

Stopped Thieves from taking my bike
Solid lock. Had to replace another one after someone tried to steal my bike by twisting the U lock. They tried again on this new lock, and while the lock is compromised now, they couldn’t steal the bike which is what counts. I’m buying again, but will keep the bike locked inside at night now..

Works!
Does it's job and keeps my bike locked up. I do sort of wish I sprung for the larger version because on some racks it's really hard to get the lock around the stand, tire and frame...but overall, it does what it needs to.

Secure enough for me / rattles a little
I use this lock to secure my bike in our building's private garage and for rare quick stops so I didn't need anything crazy heavy duty. This works well for that. It does rattle a little when using the frame mounted holder when I am riding over rougher surfaces, but not too bad.Update 6/7/23: the plastic frame mount broke after about 1,500 mile of riding on paved bike paths. Replaced it with a kryptonite mount they sell separately and that seems better made, but still plastic.

Heavy duty
This works great and slides right in to the side of my bike. No one is getting through this thing and it’s worth every penny.

Good product for the price
The lock is kinda finicky but otherwise a sturdy quality product

Do not buy!
Lock does not engage. This happened immediately after purchase, got worse and now completely inoperable. I can't believe they still sell this

Easy to use
I bought this lock for my daughter to use on her bike when she goes to college. So far she has locked and unlocked it nearly every day and has had no problems. I like having the peace of mind that her bike is locked securely when parked on campus. She does not have a place on her bike to fasten the lock to while she's riding but that's fine because she just hooks it on her handle bar as she's riding.
