content: I bought this unit about a year and a half ago, and have so far gone through 3 handsets, and the latest one has also failed. The handsets would lock up, and become unusable, and recently, they only hold a charge that allows about 15 minutes of talk time. The buttons sometimes would not work, and required excessive pressing to get the button to register. My suggestion is to steer away from this product... it's obvious that many bugs exist, and not a lot of thought was put into it's design and reliability. I'm not impressed by this Siemen's phone at all.
