I really like this brand I had the last one someone tried to cut through it it was a cable and it held up. so I was replacing it and decided to try this one outstanding recommend to anyone that's needing some type of protection to keep Intruders out or away from their items thank you very much

Impressive Lock!

I first purchased Kryptonite locks a decade ago. I originally purchased the locks for our bikes but my husband "borrowed" them during Covid to secure our travel travel from being stolen - the locks worked perfectly to secure the chains, the hitch, and our propane tanks. I recently purchased a new bike and purchased another Kryptonite to protect the bike. I trust the locks completely! My husband? Not so much. This time I will hide the keys .

I'm a convert!

This thing is amazing. I prefer cable-type bike locks because they're so much more convenient than U-locks, but I live and work in a city where bikes get stolen all the time. This gets the benefits of being easy to stick in a backpack but it's also strong enough that I feel safe leaving my bike places. It's long enough that I can fit it around all sorts of things.
