The test
1. General Information
We made an anonymous purchase of this Discover portable CD player from KLIM on Amazon France. As an independent testing institute, we carefully evaluated this product, from ordering to use.
It is important to note that our evaluations are in no way influenced by brands. Brands pay for an audit of their customer experience and for the use of our trust badge, but are not informed when we place an order.
Our assessment covers the entire customer journey, from product presentation to delivery and acceptance. We also analyze packaging, user experience and after-sales service, while assigning a value-for-money score compared with other market players.
Assessments are based on a points system, with a maximum of 100 points per section. The final grade is the average of the sections, weighted according to their importance. Details of our assessment process are available on our website.
2. Delivery (out of 100 points)
