The state of the article when you return it
If the value of the article is reduced, and the reason is that you have used it in any way beyond what was necessary to check the type and properties of the article and how it works, then only part of the purchase sum can be refunded to you. The amount that can be refunded depends on the saleable value of the article, and in certain cases this may mean that only the freight charges can be refunded.
We recommend that you return the article in its original packaging. If the original packaging is missing, it may reduce the value of the article.
