Obviously received wrong variant of an article. What now?

I recently got a graphics card adapter for my laptop (see link), which apparently had Expresscard. Was also specified as connection type. But yesterday the mini-PCIe version arrived with me, which I do not think is bad, but originally did not want. What can I do now? I had an idea to keep the cable against the right one.

Here is the link: https://www.ebay.de/...3349977796

If you get something other than the ordered, you can easily complain and insist on an exchange in the ordered part. But you do not have to, if the delivered part is just as suitable for your purposes and you are satisfied with it.

If you do not want to keep that as it has arrived, complain to the seller.

Set deadline for supplementary performance.

If the purchased item does not meet the agreed quality, it is a material defect.
In this case, you must give the seller a reasonable period for subsequent performance. This is what the legislator provides.
As measured is a period of 10 days.
If the deadline for subsequent performance is fruitless, then you have to withdraw from the contract and claim compensation if necessary.
Or you do not withdraw from the contract and can reduce the purchase price. The overpaid amount must be refunded by the seller.

GOOD TO KNOW:

Your seller is from China - but has a German VAT ID

However, revocations are handled via a German contact address.

CAUTION WHEN REVOKING!

In contrast to material defects, in case of cancellation, the buyer bears the return shipping costs.

For material defects, the seller bears all shipping costs. Both for the return shipment, as well as for the re-delivery of a new and free of defects Article.

SELLER WITHOUT TERMS

Contrary to the statutory consumer regulations, the dealer does not provide any terms and conditions (general terms and conditions) in which the warranty rights of the buyer are regulated.

It is also inadmissible that the seller allows revocation only by post.

My advice:

You should contact the seller through eBay and inform them about the material defect in this way and ask them to deliver within 10 days a new article that has the agreed quality.

Of course you have to send the item back to the dealer.

Since you are in the case of litigation, you can and should insist on the shipment with proof of shipment. The shipping costs must be paid by the dealer.

You are not obliged to arrange the shipping costs for the return shipment. The seller can send you a prepaid shipping label!

CONTACT SELLER:

The following things should be clarified:

defect
Deadline for subsequent performance
Shipping label for the return of the defective goods (cost of shipping)
No terms and conditions of the seller?
No revocation - material defect liability!

I wish you success!

The legal information about the dealer you can find, as usual at China dealers only very low on the page!
