Ok, but I think it could be better for the price, as the bottom part is made of plastic; I thought it was all made of iron.

I've been using it for a while and everything is perfect.

A very practical and high-quality lock, a good purchase.

Same as in the photo.
Rock Bros seems to never disappoint.

Good product, the key lock doesn't work that well but once it's locked it stays secure. It's also a bit narrow so you can only secure the rim and sometimes the frame.

It's not that good, but I think it's fine for reinforcement.

I really liked everything about the set; it comes with a cable and a holder to secure it to the handlebar. Even though the locks are small, they need to be quite sturdy. I chose the maximum package and didn't regret spending my money.
