International Money Transfers

[Chunkford]

Looking to transfer some money from the UK to a bank in HK in $

Being the inquisitive self I am (and always trying to save a bit here and there), I stumbled across services such as http://www.transfermate.com & http://www.hifx.co.uk

They all look good, and should save me a bit money but I can't seem to find any disadvantages.
So... can anyone here enlighten me to any disadvantages these services might have when compared to using the bank?

Ta muchly
