Anyone got secure locks for your doors?

Hey all,

I’m currently in Aalto university in Helsinki and come across a nice thing. They’re starting up business about secure locks.
Basically you can use the phone to open the lock, and share the keys via app with your friends, tenants, or housekeeping guys.
Imho, it’s time saving and easy to manage. No more need to worry about keys lost or keys cloning. They asked many including me if I can help them to see if others are also interested. Please tell me what you think with the survey here?

Thanks so much.

Of course if you are handing out review copies, I’d love to have a couple too.
