Hi, This may be a little premature, but I just started using my brand new Tria device and for what it's worth here's may round one results: Over 4 days I Tria'd 5 fairly large and different areas. Typically, if I shave one of these areas on Sunday, by Wednesday it is fairly obvious that I will be shaving them again on the upcoming Sunday. This week I shave each of the 5 areas as usual and Tria'd 2 of those areas. Over the next 3 days I shaved each of the remaining 3 areas and then Tria'd them. Today, Thursday, shaving this coming Sunday would seem pointless. For any typical 1" x 1" area that may have contained say 20 hairs and should by now contain 20 stubbly things that will need attention by Sunday, I see only one tiny lower-eyelid looking hair and maybe 10 "five o'clock shadow" type stubbly things. I know this is just my first week, but for me this is incredable. I'll try to report back in a few weeks.
