Virtually the same thing could be said to "kill" a sale on just about any regulator out there with the exception of Atomic and Oceanic. It's the same factory in China that makes makes most of them, and one is not a "cheap copy" of another.
Amazing what the desire to sell something else will pry out of the salesperson's mouth. Could be an inventory issue, could be a spiff on something else, who knows?
according to the owner at Dolphin Scuba it was exactly as Thal guessed in his above post. He is apologetic and wants me and his customers to understand that those sales tactics are NOT how Dolphin Scuba is supposed to operate.
