I wasn't referring to HOG, but since you want to go there... Before I invested in my tek regulators, I test dived a bunch of regs. I compared HOG to ScubaPro MK25/S600 on a dive to 50 meters by swapping long hose with my buddy. The SP WOB was way better than the HOG. No comparison. I had done a similar test with Apeks and thought the SP was a little better than Apeks. If I was diving cold water, I probably would have went with the Apeks. But HOG wasn't even in the final group.
As for your opinion that HOG is cheaper because the big guys spend more on marketing - HOG is made in China, where they have no health, safety, or environmental requirements (same people who use lead paint on childrens toys). And HOG is a good copy of the Apeks designs, which means they don't need to hire design engineers, conduct research, and develop products at significant expense. Combine no R&D costs, no environmental responsibilities, no employee benefits, and indentured servitude wages and you get a significant cost advantage over companies that manufacture in the west and have to pay people a living wage and not pollute the environment. Where does the runoff from the HOG plant go?
And, Quality is an empirical measurement, not your opinion. Show me data that says the manufacturing process for HOG is any better than anyone else. Which CNC machines do they use (Citizen? Tornos? a cheaper version?). What are their tolerances? How do their tolerances compare to their competitors? What is their material sourcing process? What is their reject rate? What is their rework rate? What is their customer return rate?
