The best thing I would definitely do is to put a second chain for theft prevention of a different company and color for psychological reasons, both for the thief and for us. It is sturdy, thick, cannot be cut easily, heavy, unfortunately, excessively small. For example, there is no chance it will fit around a tree, most likely it won't even fit on a lamppost, only on fences

Nice chain. It is a bit big. I do not recommend it for a bicycle as a size, unless you need a larger security. It is not completely prohibitive.
What bothers me the most is that the chain does not lock in the lock if you push it, but I have to turn the key every time.
