I made more the 15 transfers with transferwise.com and are very happy with their service, to transfer money from my regular bank to a foreign account as many of the P2P or Crowdlending sites are in foreign countries. With transferwise I saved a lot of money using their service, it's very easy to use, and a lot easier than making a bank transfer. For me, the service reminds me of PayPal or MoneyGram, just a lot cheaper, easier and with full transparency on your transactions.
It´s also possible to make transfers to bank accounts in countries like Thailand or to Pakistan.
Before you make your transfer with transferwise be sure that you always add your client ID a (normally it saves your client ID, but it doesn't hurt to doublecheck.
