The device looks very appealing. That's the only positive.
First, the phone cord supplied only fits directly into the telephone socket. If you have to connect it via the modem, a suitable cable must additionally buy.
The meager instructions is only in Chinese and English.
You can adjust the ringtone volume yet neither the ringtone itself. The ringtone sounds exactly like my doorbell. It makes me absolutely insane!
Conclusion: does top out, but can not do anything! Chinese scrap! If you hardly use the landline phone and it should only look good, it is ok. And solely it is absolutely overpriced.
