Send goods back to the seller because of shortages?

I recently ordered a product from Amazon.

Unfortunately, the goods were not quite as I imagined, i.e. The mouse that I ordered for my laptop is stuck.

Question: How can I send this goods back to the seller so that I can get my money back?

Just send it back? Or is there something to consider?

Click on "Send article back" in the Amazon account…

What Rubezahl2000 says.

It would be interesting to know which mouse it is.

In any case, leave a comment for others on amazon and remove stars.

Have noticed that a lot of comments are fake, where I think: Either I got a broken one, or ordered something completely different…
