I have bought those phones almost 3 years ago at Costco. It came in a set of 3, which I find useful since I can have one in the kitchen, one in the living-room and one upstairs so I don't have to rush across the house each time it rings. Wasn't too sure of the quality as I had bought Panasonic's two phones set for more than that and the sound quality wasn't good at all (but they were much nicer, blue and silver). Those are straight black, no fuss. They don't add to my decor but they work very well.
They are not bulky as old phones, but not to thin either, fitting comfortably in the hand without giving cramps, or squizzed between ear and shoulder they stay, it's sometime very useful.
You can store 100 numbers, which is not that bad. Each phone has its own directory and you cannot send it from one phone to the others which is a bit frustrating. But you can set all the phones for the general settings like the hour for exemple, they all update.
The range is enough for me, it goes to almost 100 feet.
As I am somewhat lazy, it's not always on its base, and so I was able to see how long they last on their battery. I'm glad to say they can stand by me a good 4-5 days if not too much calls and easily 3 days if put to work normally. Which for me is about an hour a day, combined.
And having 3 of them, if you forget one, there's always another ready, in my case, a must. I am still very glad of my choice.
