In some fields you can also enter what exactly is defective about the product or which parts are missing. Simply click through the questionnaire until you see more options. You may receive advice and information like these:

- withdraw from the purchase contract
- Create a sample letter
With the latter option, you will receive a copyable sample letter directly to the manufacturer or seller of the product.
