How long do paypal refunds usually take?

About 8 hours ago, someone asked for a refund that they payed me on ebay for something. I refunded and they said they didn't get their money yet, how long does a refund usually take on paypal?

Did they pay through PayPal by credit card or by PayPal balance?

Around 1-3 Days they have to ?check the money and take their part of it

It really depends, in some cases people can do the fullr refund of purchase.
