The devil in me thinks it has more to do with them being made by sicce who isn’t under their umbrella of brands. They definitely had a longevity issue. For me, they seemed to always make it to the 18-24 month mark. A couple months is pretty bad.
Aperture and Sicce have an incredibly good relationship last I heard.
Last time I talked to BRS about the WAV pump it had not been discontinued, but a lack of parts made them impossible to keep in stock right now.
With Aperture now owing them all, that means Ecotech’s patent is open to other companies within the company. A Neptune branded dry side that plugs into the 24v port would be pretty cool. Cut out a power brick and controller. One single cord from the dry side would be super compelling!
