After two days of using these little phones around the house and office I’m feeling pretty good about them. They’re very small, which is potentially less than ideal, but so far it hasn’t been a problem. The batteries are Lithium-Ion and the talk time seems very good.
I used one with an old Panasonic headset for a series of conference calls today. I probably spent four hours on the line. The call quality was excellent. Volume on both the phone and the headset was good, which had been a problem on wifi phones I had tried previously.
