I would like to buy a used laptop, budget about 400 euro, but I don't know whether it is better to buy it on Ebay or Rebuy.
Someone already had experience?
As far as I know, Rebuy only has Apple laptops. You won't get very far with 400 euro.
No need to ask.

However, I don't know whether it is better to buy it on Ebay or Rebuy.
You don't buy from eBay, but from a seller who only uses eBay as a sales platform.
And you should take a close look at this seller, e.g. The ratings received and whether PayPal payment is possible.
It must also be clear to you that if you make a purchase abroad, you will completely waive your usual German buyer rights, this also applies to any warranty claims.
If in doubt, you have to hope for PayPal, but that is not an all-round carefree insurance either.
Take a look at one.de
There are really good used or new ones, also for 400 euro
I can recommend refurbed and backmarket to you, the laptops are refurbished and overhauled and relatively affordable
