Of course we were a bit skeptical because of the DECT standard (radiation exposure). We believe now but just the description of the manufacturer that the phone is actually a "Smart Eco mode" used.
We use the baby monitor mostly in our kitchen in the evening, when our little one (20 months) is already in bed. The signals (also quiet Bettgeraschel) get there even through two closed doors and around two corners clear to (the bedroom is a "snap" back room, and we live by the way in the old building with thick walls).
It has been about a month in operation and we have so far to observe any failures.
The only downside:
Is a little shaky and a suspension is not so easily possible. With a little creativity can get at the but ..
As always, the delivery by Amazon was absolutely great: Even without Amazon Prime was the package after only 36 hours on our door - Thanks !!
Conclusion: strong buy recommendation !!
