Excerpt: I had the same phone system and it worked great except it didn't have the link to cell feature. I figured I'd try this one out with our cell phone connected through Bluetooth. Setup was easy but you do have to read the manual. There are things you just can't guess or find in the menus on the handset. The Bluetooth calling worked very well but I don't think it sounds quite as clear as a dedicated phone line.
Summary: The product does exactly what it promise to do. The cell phone link is so convenient and works flawlessly. After you learn how to access and navigate all the features this phone offer, you really enjoy the phone. The voice and reception are great.
Summary: Handsets are very light and easy to handle. Base has most options you would want. It even Bluetooth's with your cell phones. Only gripe I have is that the base does not have any battery backup so if you lose power the base does not function. So you need to keep an old standard phone around so that you can still get service after losing power.
Summary: BEWARE! Be sure to check the Panasonic "Cellular Connection List". If your cell phone is not on this list it may not work with the Panasonic phone. I have a 2 year old Droid Bionic and assumed it would work. The phones will pair for awhile, but not stay connected for more than an hour or two. Panasonic advertises this as a "link to cell" phone and I thought I had done my research, but the link to the list of compatible phones is not obvious.
