Juicero

When the Juicero had its moment of fame, it was going to be Pressed Juicery, Nespresso and Tesla all in one product. 

The geometric form and lack of buttons gave it a clean and modern look which attracted investors. This juicer featured an app and easy to use pouches that load into it. People caught on that they didn't need a $400 juicer to extract juice from the $7 packets. They could squeeze the packets with their hands. Or go to the store for juice. It was discontinued after 2 years on the market.

It's not enough for a product to only look and feel premium. They could've at least made the pouches harder to squeeze.
