Yes. No doubt TransferWise is a great company to use to send money abroad. Their rates are extremely competitive and they are truly one of the few disruptors in the field of money transfer (many may argue otherwise).
It is because of Transferwise’s low fees that many others had to lower their fees to compete. However, Transferwise is not the only solution provider in town. There are many others, so do your homework and ask questions.
In certain corridors, TransferWise may not be the best solution around! (gasp!) There may be other providers who beat everyone else in such corridors.
