Cons not working...
Summary don't buy it.
Pros Low Price, easy to set up, good audio quality.

Summary When we decided to eliminate our landline to save money, we purchased this device to interface our cell phones to our existing telephones. We tried it with 3 cell phones, a new Pantech Breeze, and older Samsung SG897, and a new ATT F160. The Breeze constantly unpaired from it, and the Samsung, although worked fine at first, later started having this problem in which if I dialed a call using a phone connected to it, the cell phone would dial out, but the audio would not be passed back trhough to the phone. The new ATT phone did the same thing. The only way to stop it from doing that was to cycle the power on the Phonelynx. I never found a way to solve the problem with the Pantech. I sent the Phonelynx back Amazon for a refund and bought the Xlink instead.
