I don't think the landing page is bad. Product seems cool. I don't agree with the people talking about extra features. The main issue I feel is that this is something only people with quite a bit of money and leisure can afford (because it's not solving a direct problem, it's just for convenience). So you need something on the page that will unconsciously persuade these people that it's cool. It's an upmarket product but the website doesn't advertise it as such.

Rather than doing online ads I think a promo vid with a progressive looking family / hipsters would be more effective. ;)
