Great range, can go through walls where regular bells with 120m range won't ring
Larger button size, no space for a name label

It passes at 10 m through a triple-glazed window which is clearer than 200 m in open space. I don't need a bell in an open space, I can shout it.
And it still has a margin, because the button is on the column and it also shields. And yet it rings beautifully which my last bell could no longer do.
Nothing yet.

It works great all over the apartment building.
The pairing will succeed if after a certain time ( 2-3 sec. ), stop holding both pairing buttons mentioned in the manual. The confirmation tone sounds when the buttons are released, not when they are held down as the manual tries to tell the user.
