Title: A triumph
Review: The lock itself is hefty so be aware this is not a light item. I love the dust cover over the lock. It is easy to use and very secure. I do wish I could have the yellow area in other colors, but that'd just a personal preference. Overall they did it again with another great bike lock!

Title: Perfect
Review: Not sure it needs a review, it's a pretty famous product. Feels like a ridiculously strong lock. It's heavy but I'm always carrying a backpack so it's fine. It's expensive, but not as expensive as losing your bike. Easy to open and lock too.

Title: Used to lock up my e-bike
Review: Heavy duty lock, I may or may have not used it as a mallet on a few occasions. Keys have a button function that emits a blue spot light which helps find the lock port in the dark (included spare key has the same feature). I have put this lock through boatloads of abuse and it's still working 8 years later.

Title: High Security And Heavy U-Lock For Unattended Bikes
Review: I will start my review by saying that as expected, the lock is extremely sturdy and heavy, weighing 4 pounds 5 ounces and comes with three keys. The shackle is 3/4" thick and the locking mechanism is 1 1/2" in diameter, which is a great deterrent for most of the opportunity bike theft situations since it should be extremely hard for someone to defeat the lock without the use of some power tools. The interior dimensions of the shackle are 4" wide and 10 1/4" from the top center bottom of the shackle to the top of the yellow locking mechanism which is longer and wider than most. The yellow locking mechanism also removes completely from the double-post shackle when unlocked which allows for easy securement of the the frame and rear tire (and the front tire if you remove it) to most posts. The lock exterior dimensions are 6 5/8" x 12 7/8".The entire U-lock is coated with a durable vinyl coating, which has held up well even after the lock falling off of the bike twice after being jolted off by heavy bumps. My only gripe is the black cover on the locking mechanism rotates easily if twisted and can keep the shackle from locking, not a very big issue if you handle the locking mechanism by the yellow cover instead when placing and removing the lock. The bottom of the lock has a sliding key hole cover which is easy to operate and locks in and out place. The lock uses a high-security type key which makes the lock very pick-resistant and should be far more secure than the previous round tumbler designs from Kryptonite (some can be opened using a Bic pen!). One of the keys has a built in LED light which is very bright if you need to use it at night. If you register the lock key code on Kryptonite's Website you can receive a replacement should you ever lose the keys that come with the lock. The theft guarantee had too many restrictions to be useful, so I wouldn't use that as a primary reason to purchase this lock.The reason I didn't rate the lock 5-stars is at first the locking mechanism would stick at times, making it difficult to remove the key. I used some silicone spray in the key hole which has definitely helped. The other issue is that since this is such a large and heavy lock, finding somewhere to secure it on your bike isn't easy. I hang the lock from a bracket on the handlebars that is for a front basket and the weight of the lock is sufficient to keep it from moving unless you go over a very large bump in the road. Overall this would be an excellent and high security lock for anyone leaving a bicycle unattended for long periods of time or in a high crime area. For other situations like a quick trip to the store it's probably overkill, but is great for piece of mind as long as you don't mind the added weight on your bike and have a way to carry it.If you don't have a convinient place to carry the lock on your bicycle and don't mind a shorter length U-lock, the Kryptonite New York Standard Bicycle U-Lock with Bracket ( 4-Inch x 8-Inch) might be a better choice since it basically a shorter (4" x 8") and a bit lighter (3.9lbs) version of the New York LS U-Lock, with the same 16mm shackle and includes a bracket to mount the lock on your bike.

Title: Worked well, better than lower rated reviews.
Review: The first thing I did was use a wire brush on the keys, they were very rough. Once the edges were "lightly” buffed up, the keys when into the lock very easily. The lock must be pushed all the way onto the two posts of the ring. The key must also be inserted fully into the lock before trying to turn the key. Following this the lock works well.

Title: Big, Bold, Solid
Review: The item shipped to me is a Kryptonite New York Lock MC, not the stated LS. But the looks & diamension are the same as stated. So it could be a newer model. When I first open the box, I got a shock. The lock is simply so big and long! My mom asked if that's a weapon!Yup. It can easily lock your bike and rear wheel to most metal grills /bars / bike holder at ease. Just be mindful that its heavy. But its the solid quality of this heavy lock will keep your bike safe. Well for me, I only carry this lock and a 10mm cable to loop through my front wheel and lock it into this U-lock. I trust that the 16mm hardened steel shackle is close to impossible to crack, thus its safe to use this as my sole lock.I do note that the entire lock is coated with a very nice black glossy vinyl finish. I appreciate the fact that vinyl finishing can protect my bike from scratches when using this lock since its so heavy. This is a plus point if you use the lock daily and thus vinyl surface will avoid wear & tear scratches on your bike. However, I'm afraid that after some time the vinyl surface might suffer from deterioration as the gloss rubbery surface is bound to wear off after intense usage. To counter this issue, I've taped up the entire lock using gaffer tape as a protectve measure.Ihis is a lock that will give me a peace of mind. Great lock!

Title: Beefy
Review: This is a sturdy, sturdy U-lock. Is it possible to use an angle grinder to get through it? Absolutely. I don't, however, worry about it because the metal is so thick that it would be a significant risk for a bike thief to attempt it - especially when there are many other bikes secured with cable locks and thinner u-locks around it. My only (minor) complaint is the function of the lock. There have been a few times where a piece of dirt or pocket lint slid into the lock and made it so that the key doesn't turn. Most of the time, readjustment allows the key to turn, and it isn't an issue. I have, however, been scared to be forced to walk home on a couple of occasions.Overall, I trust this lock, which is the most significant component to this review. Buy it if you're locking up your bicycle in a higher risk area but remember that any lock can be bypassed with the correct equipment.

Review: The product that arrived is different from the product in the picture. It is missing the tool to attach the U-lock to the bike, which was one of the reasons why I bought this U-lock.
