This nanny is our first, I can not compare. I like that she helps with my daughter and that I no longer run every five minutes through the entire corridor to check how she sleeps there!
Pros
Batteries in a child's cell. During the day, sometimes she sleeps on the balcony, there are no sockets. And motion and sound sensors - a brilliant invention!
Cons
I did not immediately understand that the motion sensor is a software function, and only works in the application.
