I bought the Uniden DCT646-4 2.4 GHz Digital Expandable Cordless Phone System with 4 Handsets as an impulse item and really loved having all those handsets around everywhere. I was a little disappointed that the batteries were the soldered, heat shrinked package, rather than generic NiMH ones - but that's a quibble. The phones performed about as well as my older, larger 2.4 Ghz Unidens which means:
1) Audio quality is moderately poor, with rolled off treble and a dark sonic character. This was most noticeable when I first started using Unidens (after my older Sony and Panasonic phones died). After a while this didn't bother me any more. I used Unidens for years without noticing the sonics until I got Panasonics again and was struck by the better sonics. The screen and software are better on the Unidens, though.
2) The software is pretty good, once you learn that * toggles the area code and the "1" prefix on and off in caller-id. Each phone ends up with its own phonebook, but at least you can copy them around.
3) Ergonomics are a bit dicey. These phones are SMALL! Looking at the tiny cell phone-like keypad I thought my big ham fingers would have trouble dialing. From time to time that's true - but for the most part it didn't get in the way too much. I have trouble sometimes getting the earpiece on my ear. That's a problem with most modern phones, though. These aren't much worse than the others. I guess the sleek styling trumps the ergonomic benefits of having a decent earpiece these days.

Why am I writing about these phones in the past tense? New fluorescent ballasts under the kitchen cabinets where the base station is, and a WiFi repeater combined to make 2.4 Ghz phones too noisy. I was able to use 5.8Ghz phones instead. I haven't sold these. I figure I might use them elsewhere in the house somehow. For folks who can use 2.4 Ghz phones these ones are really just fine if you can live with the tiny size. Given their performance and the huge number you get for the price (4) they are a bargain.

I just got this set and have been messing around with them for a couple of days, and have found them to be really nice for my purposes. So far, I have had a clear signal, and the sound quality of the handsets seems fine to me, and my callers have said it sound clearer on their end as well (maybe my old phones were that bad). Yes, these phones are smaller, almost like cell phones of a couple of years ago. Their is a model above this set that has an answering machine with it (about $10 more). I like this set also because each handset has built in speaker phone, you can answer two handsets at a time, and you can page/intercom the other phones. They also have a room monitor where you can call another handset and it will turn on like a baby monitor, so you can listen in/or yell at somebody. You'll find it hard to beat the overall value of this set in both features and price, as well as the number of handsets. Available online at amazon, and at some of the big chain retail stores if you like to see things in person.

I have this phone for a laboratory with multiple rooms and offices. It works great. Signal is good, phone size works well. Best part is conferencing or paging other rooms. Transferring calls is easy too. Very pleased.

This ends the problems with having different complicated phones scattered about. This set is good looking, easy to use, and you only have to plug one into a phone jack. The others you can place where you want them without worrying about the phone line. So good I bought 2 sets! Easy to handle and clear sound with all the features you need!

works great, had these for my home, bought them as a gift for my mothers birthday
