Length and strength
As always, Kryptonite quality! I like that these come in 10' length, good to use for multiple bikes or motor bikes.

Works Well for Large Bikes
Flexible and long for use on large ebike.

The keyed version is great!
Better than expected (after reading many reviews). This is after 3-4 weeks of use. Bought for my 2024 Honda Rancher 420 ATV. Easy mount on the front bumper via the included strap, and looks great. Plenty secure. Bought the keyed version, since the combination lock had some mixed reviews. Will update after 9-12 months.

Waste of Money (both key and combo version)
Failed almost immediately. The tumbler just spins and never catches the cable to lock. It is cheap, a little shorter than 6 ft, and most importantly it is completely unreliable, just like the combination lock I had for only a short while before replacing it with this one. I think I am done with this brand. I would send it back, but in my rage I threw it on the ground and the entire casing fell apart. What a piece of junk.

Lifetime Warranty and Support?
EDIT: After 9 days I received a reply and notification that they would send me a new lock. I am updating my review from 1 star to 4 to reflect the fact that they do (although slowly) support their products. I bought this lock and spent a little more than the others on Amazon because it was from a (quality?) brand that I was familiar with and came with a lifetime warranty. After some light use the lock no longer functions. It was stored inside and never has even been exposed to rain. Contacted Kryptonite customer service and got no response. Sent a new message after 7 days and still nothing. Extremely disappointed in my purchase and customer experience.

Versatile Protection
Having two approaches to opening this cable lock, one with key and the other with combination, is the best of both worlds for me. As I age, sometimes the code or combination eludes me and it makes sense to have a plan B in case. Overall construction is solid, the lock mechanism smooth and most important...it works! Four stars are the score only because the stiff coil of the cable really can fight you when two hands aren't enough to keep everything in place while you lock up. Tough balance in design since the cable is so beefy for a secure result.

High Quality Bike Lock
This seems to be a very good option for our suburban parking needs. The grocery store, local restaurants, etc. It isn't used in a high theft area, so I expect it to work well. The coating around the chain is a nice quality plastic. It isn't too heavy. The length is actually rather dramatic. It is a little expensive, but seems well worth it.

Good lock
Very sturdy bike lock for the price and is better than those costing twice as much.

Within 3 weeks of using the lock it jammed and would not release, had to cut it off. What a disappointment in what I thought was a quality lock.

L'antivol constitue un bon compromis, il est pratique et semble solide La longueur est suffisante et il est possible, avec la patte de fixation, d'accrocher le cadenas au cadre du vélo lorsqu'il n'est pas utilisé Je regrette simplement que la clef ne reste pas solidaire du cadenas lorsqu'il est ouvert, comme j'ai sur un autre antivol *** MISE A JOUR *** A l'usage il est certe pratique, j'avais signalé que je regrettait que la clef ne reste pas accrochée au cadenas lorsqu'il est enlevé. Cela se vérifie car il n'est pas nécessaire d'avoir la clef pour le fermer, et donc je me suis retrouvé à 20km de chez moi avec le cadenas fermé et pas la bonne clef avec moi.... résultat un commercant m'a prété une pince et en moins de 5mn le cable était coupé ! conclusion achetez un U qui sera plus difficile à couper !
