I was able to get one to test and it just arrived two days ago. I just got the single head because as pointed out, two heads seems a bit useless but each to his own. Build quality seems quite good, The cable is a little stiffer than I would have liked but doesn't seem to bother me, 48" which for me seems like an ok length. The goodman handle is actually quite nice and fits perfect with dry gloves. Wouldn't want it any smaller. The light head seems to sit a little far forward on the handle making it feel unbalanced out of the water but in the water with the dry gloves on it wasn't noticeable. The only issues I note so far are that the switch on the light head seems a little flimsy and slightly smaller than I would like making it a little difficult to turn operate with dry gloves but time will tell. So far I just took it on one shallow dive to test it out (just over 12m/40 ft, in 7C/45f) but it performed well. A lot of rain recently so there was high turbidity and back scatter was a bit of an issue. Not sure what the beam is but for really mucky water a tighter beam would be nice. Won"t be sure till I can take it deeper which might not happen for a while due to other commitments. First impressions though are quite good. Blows my old DIY light out of the water and right up there with the Light monkey and Hollis lights I have used. Like I said though, until I take it into the really deep cold water I won't have a true test. and only time really tests anything.
