Does not work right!!! Connects only in a central location in your home. The blue tooth range is a little weak at about 20 feet. It connects automatically most of the time but not all the time. Not sure why but it eventually connects if not right away. The sound quality is good when it works but it doesn't answer on the landline most of the time.
If it worked right it would be a great unit that lets you leave your cell phone charging in one room and have access to it throughout your house if you connect it to the wiring in your house (isolated from the original feed into your house). It works with two cell phones. Note: since it uses blue tooth, playing voice mail will try to play through the land line instead of the cell phone. You must disconnect from blue tooth to play the Verizon enhanced voice mail messages or most applications that use blue tooth.
Works as advertised. Plugged it in, synced it to Bluetooth and it has worked flawlessly ever since. Very quiet strong connection. Disconnected ATT at the demarc box, plugged the Cobra into aa AC outlet & spare wall phone jack and all 9 house phones ring and operate as expected. Saved about $80/mo. Wish I had done it sooner!
I have an iPhone 6 and thought this was a very clever product. But, I have to be in the same room with it to use it.
Not only that but when I leave the room I have to reconnect the Bluetooth using the settings on my iPhone. If it had a better range I would have liked it a lot more.
The first one of these I bought worked well until I placed it on the carpet and it overheated and was never the same again. This one seems to work on a hit and miss basis, it just seems like they need to put more work into it. If it worked as it said it should I would have no problem recommending it.
By the way, I use an iPhone.
