Yes I do Bill. I've using it since shortly after picking up the HX100V back in march of 2011.
It is very useful that it automatically updates the satellite date on the SD card and then in the camera when reinserted .... without having to use the full-blown PBM or now PMH software as you well know.
That seems to work as advertised .... it thew me off when I went to turn off the DST and found that the on-board clock was a couple minutes slow, ..... which presumably is kept spot on when it locks on to the satellite signals?
I'll keep an eye on it over time and see how it does going forward. Thanks for the suggestion!
