I expect no megaphones but I'd like to go at least 5 meters far away without the device always have to take, but I think it's just too expensive.
The intercom device (which we used only once in the dry tests) is not functioning properly, one understands the spoken words on the baby unit does not run smoothly. But since we always keep this feature unnecessary, this would still not have mattered.
The sensitivity of the device, however, is unbeatable - in cracked window you can hear the cars on the street over, the game clock in the nursery you can hear even silent strum (if you hold the parent unit to the ear)
Conclusion: In general, a great device, but that's failed for our needs through this one deficiency.
We sent it back. He that hath an ear fox but have fun with it.
