Ada is a brand. They need to protect their pricing structure. People will pay for it because they can brag about it. Competitive products who look the same and cost less is already on the market, but people will not save or settle for them because it is not a high end product. That's why do aqua is there, for people who want to save. This is the reason why people won't buy a Hyundai genesis over a Mercedes s class or a BMW 7 series. You don't have the brand. They have the amano name and that is classy.
