How safe are rim locks? Are they universally usable? What do I have to consider?

Hello, since I’m about to get my new car and this really nice 16″ LM wheels on it, I want to protect them against theft. Do such 27.95 Euro rim locks do something and how do they work? Maybe I also want to secure the rims of my wife’s M2, but I don’t know if this nuts or screws have. Can I buy the same? It’s primarily about making the “fast” thieves unattractive, who use the opportunity without any effort to klakla Professional thieves will certainly not be deterred by this. As always, I am grateful for helpful tips.
