Nice gadget and a nice help

I bought this keychain a cool trailer to have for my car keys. But he has real advantages!
I've tried the belt cutter already (do not worry, it was not an emergency) and it works fine!
Even the emergency hammer I have already tested and was amazed at what comes out of this little device.

To me it means now, I'll leave this as long as he holds my key to be prepared for possible dangerous situations or emergencies.
A real buy recommendation!
