## Description

CATENA CON LUCCHETTO INTEGRATO KEEPER DA 120CM

Review: I am really impressed with the lock. It strikes a great balance between price, weight, and sturdiness. I feel more confident when securing my bike trailer with this lock. I've also heard that this type of lock is more difficult to pick, and I hope that proves to be true. Overall, I highly recommend the Kryptonite Keeper for anyone seeking reliable bike security.
Review: J ai acheté cet antivol pour ma trottinette speedway 5 . Elle passe sans problème dans les interstices en aluminium et assez longue juste comme il faut pour pouvoir l'attacher. Toujours satisfait de la marque kryptonite . Elle fait son petit poid mais ça reste raisonnable .

### ⭐⭐⭐⭐⭐ Review
*by D***R on 9 July 2023*

I bought this to replace a cable bike lock I was using, as trying to uncoil the wire was time consuming and irritating. While I don't think this would prevent someone determined to steal your bike, it's very sturdy and will buy you time. The unit is kind of heavy but the sleeve around the chain makes it very smooth and comfortable to work with. As people have mentioned, the key is a little tricky to get in the right way as there seem to be multiple free rotating discs that need to be lined up for the key to be inserted all the way. I suspect this is an intentional design to combat someone trying to pick the lock. Overall I'm happy with it.
