Is this a critique of the marketing page or of the product itself?

I didn't intend for this to be about the marketing page -- what you say is true of just about every marketing page. They're prevalent because they are good at distilling information without overwhelming the user. But I agree I can do better and will work on this more, I really appreciate getting this feedback

Most people look at pool chemistry/maintenance as painfully overwhelming, so for everyone to say this looks boring or mundane is a bit validating. No one has (yet!) said they don't understand the product, it's purpose, or it's value :)
