Summary: Giving two stars. The first month I got them, I would have given five… I bought three for my small staff. At first, were great, though took a bit of getting accustomed to switch back and forth (not super-intuitive design). After several months, one by one they would no longer would switch between mobile phone and desk phone. Then, would only connect to one or the other... One stopped connecting to anything. Overstock said I had to send to Jabra directly for service.
