I've used this lock for a year and have had no problems at all with it. It's so convenient to not worry about keys, and if my friends need to borrow my bike I can just tell them the combo over the phone, so they're happy too. Just make sure it is long enough before you buy, because mine works on my commuter bike but is too short to accommodate both the front wheel and frame on my mountain bike. Oh, and DO remember to close the weather guard so if it rains the numbers don't get wet and slippery...that can be a minor annoyance.

I set the combo per instructions. Tested it 3 or 4 times to make sure it worked like I got it. Then a little later just before a ride I tried it one more time and it wouldn't open. One of the dials is really hard to turn, so maybe that's the cause. For some people it works fine, others it doesn't, so just know that you are taking a chance. I'm returning mine and going for a key lock.

The worst thing about having a heavy duty U-lock is having to carry it around. This Kryptonite lock with the addition of the mounting bracket solves that inconvenience. I have a Trek 7.3 FX 17.5" and it mounts on the bicycle perfectly. It goes on my bicycle next to the rear wheel by angling the bracket 90 degrees. It doesn't interfere with my cycling motion and has about an inch of clearance next to the rear wheel. The lock does chatter a little bit when it's mounted, but I solved that problem by using wall insulation and duct tape. Now the mounting bracket holds the lock securely and quietly. Another annoyance with the lock is the difficulty of rotating the numbers sometimes. The best way to get around this is by only changing one number when you lock your bicycle. This makes it very easy to open it quickly. Overall, this item still deserves five stars!

I've explained how the lock works and all.

I purchased this lock in 2008. I've used it on my bike, outside, in Alameda, CA (plenty of rain). I've had to oil it occationally to keep the tumblers moving. The one sign of wear is the rubber gaskets at the top of each end of the "U"; they've weathered and cracked, but it doesn't seem to have affected the lock.

I think that as long as I oil the mechanism every now and then this lock will last another 5 years.

It's soooo great to never have to worry about a key.

Looks like people either love or hate this product. I've had mine for over 5 years since the whole bic pen controversy was widely televised on the news media as a `how to' in popping ULocks for thieves. I appreciate that I don't have to carry a key for it. I bike commute, and ride regularly for errands and fun, so I can vouch that this one can last when not abused and maintained just like anything else.

The black plastic cover for the dial lock slipped off years ago, and it went right back on, but I noticed it's removal in no way altered the locks performance so I just tossed the unnecessary component/dial cover.

I'm able to lock my rear wheel and frame to a post and then run my cable through the front tire, so I don't see the big deal about it being smaller than a traditional Kryptonite lock for which you also need a cable, but hey, if you want to carry the extra weight that's a personal decision.

I've never had a problem with the dial sticking on a number, and if you do I would recommend some WD40 before you return it and go through that hassle.

I wonder if they changed their manufacturer since I purchased mine because many are complaining of a shoddy product. I was just checking Amazon for a friend and after seeing these reviews I probably won't recommend this lock because so many people are complaining about it. Kryptonite should listen up and make this product more reliable or offer at home-based solutions to these people's concerns. It's unreasonable for someone who uses their bike daily to be expected to be lockless while Kryptonite processes the exchange.

That being said, I think this product is worth a try if you lose keys, forget to bring keys or if you've ever asked others if they have seen your keys while their actually in your hand. Happy riding everybody!

This lock broke and became effectively useless after two weeks of moderate use, averaging about two locks/unlocks a day.

I had the same problem a few other reviewers had: the plastic knob to open the lock broke off, which renders the whole thing a rather ugly paper weight. I'm now living 300 miles from where I bought it (I just moved), so I can't return it there. And I'd send it in under warranty, but I urgently need to buy a new lock. Thanks, Kryptonite.

I paid less than $[...] for this lock on sale and for that kind of money a Kryptonite lock is a great deal. That said, this lock has a couple of shortcomings in my estimation that have to do with the combination wheels. First off, they are generally difficult to turn. They just do not have sufficient knurling to facilitate good thumb/finger traction. Second, the combination wheels are chromed and the indented numbers are filled with black paint. This makes the numbers almost impossible to read under the glare of a street light due to the reflectivity of the chromed surface. Other than those two complaints, I am very happy with this lock, it's solid, compact and yet large enough (barely) to allow me to secure the frame and front wheel to every rack I have encountered without removal of the wheel. http://www.amazon.com/gp/product/B000LPHO2Q/ref=cm_cr_rev_prod_title

Although it's a little shorter than the standard Kryptonite, it is lightweight and works well. I have had no problems locking or unlocking it, as opposed to my last U-lock which stopped functioning and had to be sawed off.

Worked for a week, then my daughter called me from the store, could not unlock her bike. An hour later, after driving to meet her and banging on the lock for 20 minutes, it finally opened. Next step would've been to cut it off. It's reckless to sell a lock this bad, if she'd been on her own the bike would've been left overnight "locked up" by this junky lock. Totally different than the one I've used successfully for years so Kryptonite must've outsourced the manufacture. Bad idea. I returned it and switched to a key version, different manfacturer.
