Solid lock
Heavy duty lock and selectable combination. It is heavy, but it works great and I can't remember what I paid because I bought it a ways back. It does what its supposed to do and works like it should. I would buy it again.

Recommended for a daily use because of the easy of put a password instead of having a key

It's a good easy to setup and use lock but these locks some how lock you OUT!
I was easy to set up the combination and to use to lock up my bike. Update May 2024: This is the SECOND kryptonite lock I have purchased in the past 4 years. This one is 11 months old. BOTH locks suffered the same flaw which turns them into paper weights. Use at your own peril. I last used this lock on a trip to do some cycling in March 2024. I locked the bike up on the way there and on days after I rode. The lock worked flawlessly. When I got home I locked the lock up and left it in my car for another day. When I went to use it early May 2024, I could no longer open it. I have no clue how, with no intent I locked the lock with a new combination. Now, the reason I own this lock is due to the fact that the SAME thing happened to me on my previous lock in the spring of 2023, why I got this in June 2023. A replacement for the other unopenable lock! I was lucky, both times that the new combination took effect while the lock was in my car. Not while it was securing a bike. I cannot imagine the problems and frustration arriving at a ride after driving 100-300 miles to find the lock unopenable and having my bike permanently attached to my bike. Until one learns the issue or Kryptonite fixes this FATAL FLAW, use these locks at your own peril.

This is a great bicycle lock
A great bike lock, lightweight but strong. I like one without a key, which sometimes gets lost, and the combination set lock is great on this one is easy to use.

Easy to use
Cable is flexible enough to use. I secure my front gate with it. Combination dial rotates smoothly.

Good quality budget lock. Feels well made and strong enough to slow a thief without bolt cutters.

Leggero e resistente
Ottimo lucchetto che uso per bikepacking, leggero da portare agganciato alla borsa da sella, combinatore al posto della chiave molto pratico e cmq sicuro. Inoltre è molto resistente come meccanismo. Il marchio poi è una garanzia! Ho altri prodotti loro.

Solide Qualität, aber begrenzter Einsatzbereich
Solide Qualität, aber begrenzter Einsatzbereich Kryptonite ist bekannt für seine Produkte, und auch hier passt die Qualität. Ich habe generell meine Bedenken bei solchen Kabelschlössern – für Fahrräder oder Roller bieten sie aus meiner Sicht keinen ausreichenden Schutz. Für Helme ist es eine brauchbare Lösung. Mittlerweile nutze ich dafür jedoch bessere Alternativen. Unterm Strich: solides Produkt, aber für meinen Bedarf inzwischen nicht mehr relevant.
