The longer a product’s guarantee period, the fewer people want a refund.
Products often come with a guarantee of more than 30 days because a lot of people don’t take the time to look deeply at what they’ve bought within a month.
With a longer guarantee period, people are more likely to be able to look at what they’ve bought, appreciate its value and stick with it.
Plus, a longer guarantee period tells people that they can be as confident about the product as its creators.
