I understand what others are saying, for example, that someone can steal your bike with a cutter, but with this logic, even if you put a thick chain, they will cut it with an oxygen welding. I have been using it for 2 years to temporarily lock it during a movement, as the bike is stored inside the house when I return. For its price and sturdiness, I find it satisfactory.

It doesn't protect against anything. With a kick, the lock breaks or in seconds with a cutter. Don't expect it to provide any security. It might be useful for locking a cart or something else, but not a bicycle

Collected and nice to carry on the bike. Now for safety, I hope I don't need to find out if it's good :p
