I've used Transfer to send money from Spain to the UK, and from the UK to Spain. To be honest, from Spain to the UK, the money was sent faster, around 2 hours after I made the transfer to the Estonian Bank. In the transfers from the UK to Spain it took around 2-3 days. Perhaps the problem was I paid with a debit card rather than with a bank transfer.
