What do you have to watch out for if you want to sell a laptop on Ebay (with SSD)?

That the data on the hard disk is deleted and the sectors are overwritten several times so that they could no longer be produced

Honest item description, shipment-tracked shipping and very important:

Do not offer PayPal.

Photos as good as possible
Item description as accurate as possible
If problems exist; call
Safely delete the disk (data theft)
Do not offer PayPal, only transfer
Shipping as a package (with height insurance if more than 500 euro value)
Do not send your laptop until the money has been credited to the account
No shipping abroad

What is a height insurance? And why not a Paypal?

A package is insured at DHL up to 500 euro. But if the goods are more valuable, and the shipment is damaged or lost, you will not get the full value back. Only if it is covered by appropriate height assurance (up to 2500 euro / to 25000 euro).

Because Paypal is hostile to salespeople and you give the customer a 3-month right of return.

The buyer would just have to claim the goods were damaged or got the wrong currency, and PP will post the money back.
