Fast, reliable, transparent and inexpensive.
I send money back to the States every single month to pay bills and build up savings back home for when I return.  I've used Wise for quite a while now, having switched from another outfit that was unreliable and expensive.  That outfit has since been sold to another company that's even worse.  Why deal with this?  Wise is easy to use, fast, reliable, transparent, and less expensive than others I've found.  Believe me, I looked around.  Transferring money from the UK to the US is as easy and frictionless as transferring money from one account to another *in your own bank*.  Thanks guys!  You have made part of the life of an expatriate easy.
