I don't see this becoming a single button for ever item in the house. I see the Dash button riding the middle ground between objects that you have highly predictable usage patterns or have a proscribed life span like toothbrushes where recurring orders make sense and less predictable items like paper towels where usage is harder to predict.

I think the goal is also to make using the button easier than just opening the webpage and ordering it so that when you notice you're running low you can just press the button instead of doing what most people do and adding it to a grocery list. It's also far easier than figuring out how often to set up the recurring ordering.

Their aim is at the utility closet and bathroom consumables like soaps/detergents, paper towels, and maybe cleaning products. Things that are stored an some particular place in the house where when you're getting low on X you push the button and get more 2-3 days later.

Or have it built into the bottle, perhaps even measuring the current fill level.

Like inkjet cartridges, it can simultaneously add electronics to landfill while increasing your spend on consumables!

Unless that's a refillable bottle that you don't throw away that would add a huge amount of waste and cost to every product.
