SmileDrive is unique in more ways than one! First surprise is the "Battery-Less" Transmitter unit and the second surprise is its range - in my case while the main Bell Ringer is installed in the middle of my house the Transmitter unit is almost 100 feet away.
My one advice to the Manufacturer would be to make the Transmitter Unit bit more sturdy because it's always exposed to the harsh weather outside be it dust, heatof the sun, rains or winters.
In case I wish to get another Transmitter Unit...

Nice

Its good , range and sound also too goos

Initially loved the product. But stopped working after 2 month of usage. Only the light is blinking and no sound. Don't know how to repair it.
