Sure some have dove the HH unit. The ones I know (there might be others) that responded on this thread are:
jradomski - instructor
mixaddict - instructor
diverklondike - diver
heyydude - the manufacturer
Each of them can respond if they wish but you might also find some of your answer using the search function.
