How do you feel about returning items that are genuinely bad products or are not fit for your purpose? Not faulty, they are functioning as intended. There are very few things you can adequately demo and reviews only go so far (if they even exist for a specific product). Surely with the amount of
garbage deals posted you've bound to have purchased some duds.
Example 1: You buy a budget android phone and it is very laggy for even basic UI navigation or regular apps.
Example 2: You buy a battery powered tool (vacuum, gardening, DIY) and its underpowered for what you need/reasonably thought was possible for the product.
Example 3: You buy expensive earphones and they sound terrible to you or don't even fit in you ears.
