The Powerup Dart crowdfunding project was very successful, raising over 6713% of its funding goal. It had a simple idea of creating an app-controlled paper airplane that could have aerial battles. Its campaign video showed the story and creator, making the product feel personal and appealing to children. In contrast, the Smarty Ring promised to be a smartwatch condensed into a ring but failed to deliver on its promises, leaving backers angry and damaging the company's chances of future success. It is considered one of the greatest crowdfunding fails for promising too much without a developed product.
