    This lock has several faults

    After some weeks of usage the inner cylinder did not move smoothly anymore, so more force was required to open the lock. As a result the key which is made from very soft material got twisted and could not be used anymore.

    Furthermore water enters easily into the lock’s mechanism. This makes the lock useless for winter conditions – the water inside will freeze and block the mechanism so you just can not open it anymore.

    The lock itself is great, but if you want to be able to attach it to your bike frame for storage, pick a different one. It comes with a piece that you can screw onto the frame of your bike, and the lock slides onto that piece so that you don’t have to worry about carrying a big lock around. One problem with this piece is that it absolutely will not fit on a large-framed bike like a mountain bike, even with extra-long screws. The other problem is that the piece attaches to the side of the lock instead of the base, so the length of the lock must run parallel to the part of the bike frame it is attached to. Therefore, the only part of most bike frames that will be long enough to accommodate this lock is the top bar between the seat and handle bars. But to keep all of that clear of the brake and gear lines that run along the frame in that place, you have to install the lock-keeper sideways, so the lock is in the way of your legs while you ride. Basically, unless you have a bike with an extremely large but thin frame, you won’t be able to use the lock-keeper to store your lock.

    I bought this for a new bike and within a couple weeks someone came and cut straight through it with bolt cutters. I was told that u-locks were generally strong enough to withstand cutters, but this lock was not thick enough to hold up.
