Wireless telephones, God knows I've eaten in, or they were too sophisticated functions with 1000 I did not use, or they were too basic, the caller's number is not displayed, and I brigaded rediscovered for a one-hour conversation with the old girlfriend idle, unable to move. And so on of the best. This time - this, I made the right choice (for me), this device is perfect, I know who calls me, the device works with two rechargeable AAA batteries (included) and even though I sometimes unplugs for peace, the batteries are still the cleat. Autonomy is generous 16 hours of talk (you must already find something "furnish") and 180 on standby! More than a week! No need to jiggle to take coordinated and juggle the receiver, the speaker without echoes lets put it down, talk and go about your business (not kidding!), At least it provides a range of hands ... Using it is a cinch, last number dialed, received all is simple as a phone call ... and at this price, I achèeeete!
