Allison: Got this lock to replace my other one that rusted. This one is super strong and easy to use. The keys are reinforced and show no sign of breaking anytime soon. I love the heavy weight look and security this lock offers. No complaints!

Wes: The lock is good just not very big and the cable is way too short but it all gets the job done

Amazon Customer: Haven’t had anyone try to tamper with it but it’s built well enough and comes with nice keys.

Cindy: these locks are smaller than i thought they would be but they seem very heavyweight and the silicone covering is nice. The cable is also shorter than I thought. Fits my small bike well (able to loop both wheels) but I will reiterate my bike is very small and the cable just barely fits around both tires. Seems like it will do the job well though.

Mark L: Very strong lock, much thicker than some others available and I daresay impossible to cut through. The lock isn't quite big enough to fit around the front wheel and frame, so I use the included cable for the front wheel which is a bit awkward to carry around and not quite long enough to reach the back wheel too. Minor niggles aside its a good quality lock that does what it says.

M. Karl: The u bolt is fat and made of solid metal, but the receiving lock is light and thin in places, not very solid. The attachment for your bike is also awkward and impractical, because it does not form a straight line and is wider than your bike frame. Also, unless your bike frame is very thin, he only place you can attach this lock when not in use is under your bike seat.

Paul B: Quite easy to use and also fastens quickly to your bike when riding if you use the lock holder. Do note that the lock won’t sit completely flush with your frame and it will be offset due to the holder having a 90 degree turn. This hasn’t bugged me too much but occasionally my foot will make contact with the lock when pedalling.

Jordan: I bought this for school the bike lock itself is great smaller than anticipated the only problem is the contraption to hold the lock onto the bike it is made cheap I had to remove a small piece to fit it on my bike still would recommend because of its amazing price compared to other products.

restless margin: this lock was exactly what I needed to secure my bike when I go to the grocery store, stop for lunch on ride, etc. it may not be sufficient for locking a bike every day, all day in the same location. the metal is vinyl coated, so it looks and feels good. Of course, you then can't see if there are any weaknesses in the material, but neither can a would-be thief. the key mechanism works very smoothly, the mounting bracket is well-designed, and it comes with 3 keys (so you can lose two before you panic). it has a covered cable lock too. the only negative is that the "U" is rather short, meaning that can't lock the frame and back tire together to a rack unless you use the cable. Overall, outstanding for the price.
