Kryptonite Keeper 785 Integrated Chain Lock - black

I've had the lock for over two years now, and it has always worked well. It's not too heavy, and you can comfortably wear it around your neck (people who are MUCH slimmer than me can probably wear it around their waist ;-)). It has also never frozen, which ALWAYS happened to me with the U-locks from Kryptonite. But now I have to especially praise this thing: Recently, someone tried to break this lock twice, and my bike is still there! The first time they tried to freeze a chain link. What they managed to do was make an ugly dent in my frame while trying to break the chain link (with a hammer or something). Two nights later they tried with a bolt cutter (there are cutting marks on several chain links), but you can only get through hardened chain links with a hydraulic or at least a 750 bolt cutter. So, once again, a special praise for this lock (still, I've additionally got a Messenger Plus U-lock - better safe than sorry)!

I got the lock for my enduro. I wanted a stable lock but also didn't want to spend a fortune on it. The lock seems very stable and accordingly has weight. Unfortunately, it sometimes acts up a bit when opening. And that's even without any "environmental influences." But for the price, it's still a good lock.

I searched for a long time for a lock that makes me feel secure when I leave my bike locked in the city.
Here, not only does the quality fit, but also the price-performance ratio.

I bought this lock for my second bike.

It makes a very stable impression.
Only the housing in which the locking mechanism is housed seems a bit flimsy.

Otherwise everything is great!
