I've used the service for data transfer from the US to India. I've needed to transfer 20 GB of data from one server to another. The service is easy to use and the user interface is very intuitive. They also use high speed internet connections which makes things very quick. The service supports multiple protocols like FTP, SFTP. The support is also very friendly and easy to deal with. There is nothing to dislike about this service. I've used the service for several projects and have been very satisfied. The price is also very reasonable. I would highly recommend this service. I've used the service for projects with a variety of sizes. Everything has been perfect. The customer support team is amazing. They are so helpful! I have never had an issue with them and they always get back to me quickly. There can be some lag time between when you send files and when they receive them. This isn't really the fault of their software, but more of the server speed. We use Masv for our video production company. It has made transferring files from one computer to another super easy.
