content: I bought this phone because of its features: Caller ID, answering machine and expandable. But sorry to say I agree with most of the reviews of this phone. When I'm talking on the phone the other side of the line couldn't hear me for half of the time. I use the phone the first when I call my mom who's oversea and she said 'Why are you talking to me on a cheap phone?' It's not fun using this phone when calling long distance when I'm paying for every single minute, not even fun when I paid $130 for the phone, not at all. After reading the reviews I do realised that the caller id always have 'incoming' call and yes it is slow to show the number that's calling. I'll sure to try the method a review pointout to improve the function of the caller id.I had not have any complaint about the battary life maybe because I don't talk too long a time.If I had read the reviews before buying the phone, I don't think I get this after all.
