No, I didn't mean it that way.
There's a joke about this when a man comes to a urologist and tries to get a consultation stating that this his friend who actually has a problem.
So then the urologist answers by a asking a man to get down his pants and show him that "friend".
Jokes aside, I would say that Willhaben is pretty trustworthy. But Cyberport (who offers these ultra-cheap laptops) is cool as well. Make sure that you pass this information to your friend. ;)
