This is absolutely the worst Panasonic product I ever purchased. If you read the description on the box you'll be impressed. I was. Reading the manual will reassure that impression. But try to actually use the product and you'll wish you bought something else. I am a software engineer with a strong technical background in hardware engineering, so take that into consideration when you read the rest of this review.
The handsets have such an underpowered CPU that the display cannot keep up with my button presses. Say what?!? Yes--if I try scrolling through my contacts list or caller ID history, the phone beeps with every press of the up/down keys but the LCD simply can't keep up and I have to stop & wait for the display to update before I push the button again. Totally unacceptable.
Link to a cell phone via bluetooth? Yes, works exactly as advertised, and it's the primary reason I purchased this system. The setup procedure couldn't be more simple. But that's where the Panasonic design team apparently went on vacation and left interns in charge.
You never need to dial "1" when dialing 10-digit numbers on a cell phone, so I never save them that way. Neither does anyone else I know. Incoming calls on a cell never show the "1" either, so creating new contacts from call history don't store the 1. How about caller ID on a landline? Nope, it doesn't show the 1 either. So now I have hundreds of contacts stored in my cell phone without the 1. But you almost always need to dial the 1 on a landline. Panasonic has a nice "number edit" feature that, when calling from *landline* caller ID history, you just hit a button and it automatically prepends the 1. Awesome! But this feature does not exist if you want to make a landline call to contacts stored in your cell phone. This very small oversight renders the entire system useless. I don't have decent cell reception at my house, so the main reason I bought this system was ability to link my cell and only manage a single contacts list, in one place, that will always be with me no matter where I go. Isn't that the whole point of the link-via-bluetooth feature? Unfortunately, it's just not possible. The best you can do is find the contact you want to call, write down the number on a piece of paper (or try to remember it in your head), and then cancel & renter all 10 digits manually after first dialing 1.
Words cannot adequately express how disappointed I am with this product. It seems the Panasonic team tried to think of everything, and in a way they did--they wrote down a list of all the cool things this phone should do. They listed those things on the box, and that convinced me to buy it (bravo to the marketing team by the way--top notch!). But when it came time to execute, they failed miserably. It's a bad hardware implementation and an even worse software implementation. I hope nobody got a bonus for this. When I purchase a phone system, particularly one with a 3-digit price tag, the most important thing to me is that I can actually use it to make calls. I don't care about fancy ring tones, ergonomic style, color, etc. I think I set a pretty low bar. When I push a button, the display should react immediately, not wait for some noticeable delay. And if you tell me I can link my cell phone and make outgoing calls, I expect to actually be able to do that. Sadly, this product falls far short of my expectations.
