We also upgraded from a perfectly functional set of Panasonic wireless phones. The additional cell capabilities make it worth the money. We'll give the old set to one of the kids. Granted, I am still in the honeymoon phase, but the initial set up and install was instant. After that I spent 30 minutes pairing up to cell phones and testing that. Works great. Downloading my cell phone contacts worked right out of the manual. My wife's cell phone required her to take action on the cell phone while the Panasonic system was looking for entries via Bluetooth. Then we went through and deleted entries that we didn't need. All that took about an hour and a half, but it worked. Both our cell directories are now available from the home phone. Sweet. It reads the names in the phone book and announces calls from those numbers by that name. Very nice. My wife works from home. Now she can use the land line for 800 numbers without burning cell minutes, and the cell for long distance without incurring charges. All of that from the same handset. She can use her headset with the handsets or use the handsets as speaker phones. The phone rings all through the house even if work calls her cell phone and she is away from her desk. This is really nice for home office users. I have an on-call cell phone. Now I don't carry it around the house all the time. It just rings the phone. The cell phones stay inside while we are in the yard or by the pool,, but we still get our calls. At this point I only have one request for Panasonic. I hope they are reading. I'd pay for the ability to hook up more cell phones. Right now I need three, but I could see a family needing more than that. I would pay for another Bluetooth radio so two things or more could happen at the same time. Now that I have this, I'd probably pay up to double the system price if it added more paring. Well, okay, two requests. An optional type of handset that had more volume on the speaker feature and a mic volume option would be nice. Meanwhile, I will enjoy what I do have. Great features and the same great phones we always had. If you like your current Panasonic phone, you'll like this one with more features. If you don't have a Panasonic phone system then consider these. They are the only wireless phone systems I'll buy anymore. They just work.
