Works without any problems... is more the problem with the Nuki... because of its power, the part is extremely loud...

Is not a problem.

It works great for me. The door has to lock twice and has no problems. Just remember that if you need the system for the front door, you have a cylinder that you can also open when a key is in the lock. The system has already hung up on me and I had to open the door with the key.

The force is enough for me - I think Nuki is very powerful. The decisive factor is simply that the door closes correctly, i.e. all the latches don't jam.
