I use this at work in a medical office and I am happy with it. The drawback for me is that if there is more than a couple of seconds of silence, the battery saving device kicks in and shuts it off. Then I can't hear anything. I shake it around to create some noise and it turns back on again. Sometimes I miss a few words of what the patient is saying and that is a problem.  It connects and disconnects easily without other employees having to bother with it (a big step up from the amplifying cap that fit on the ear piece.)  This is a good product and I would use it at home if I had a chorded phone.
