And the reviews are in:
"Divers thought the ST1 was one of the 'smoothest breathing' regulators of the bunch and gave it the highest ergonomic scores of all the regulators in this review. The comfort swivel helped boost comfort scores and test divers had praise for the user control knob and soft purge cover. This reg also received the highest score for Ease of Breathing and was the only reg rated Excellent by test divers for dryness. When we polled our test divers for their top reg in the price category, the ST1 was a clear Testers' Choice." - Scuba Lab
