I have 14 regulators, 4 apex, 4 scubapro, 2 diverite, 2 aqualung(oxy model) and 2 x stream (my childs like the Xstream
) and i am not an ansti test machine and the right regulator for me is the right price(in the company that could assume the spare part)
i am happy with my dive rite, apex and scubapro
